2002 ASEE Annual Conference and Exposition: Vive L'ingenieur

作者： Gregg, Michael H. Goff, Richard M. Division of Engineering Fundamentals Virginia Polytech. Inst./State Univ. Division of Engineering Fundamentals Virginia Polytech. Inst./State Univ. Blacksburg VA Virginia Tech's Gn. Eng. Program Frith Freshman Eng. Laboratory

The international context for first year engineering students is discussed. Many students enroll in the College of engineering at Virginia Tech with a substantial dossier of Advanced Placement, International Baccalaureate or transfer credits. These credits complicate the process of filling a student's schedule without enrolling the students in higher-level engineering classes. Students taking the initial offerings will be surveyed and interviewed later in their academic careers to assess the impact of this course on their undergraduate experience.

An innovative new freshman engineering initiative called engage has been fully implemented at the University of Tennessee. This is a comprehensive approach to meeting the educational and developmental needs of our freshmen. Extensive data on student performance was collected during the two-year phase in of this new program. Results presented include retention rates (engineering college and university), progression through the program, performance on common final exams and performance in sophomore courses. Comparisons are also made between the engage program and nationally administered surveys, i.e. Pittsburgh survey on engineering student attitudes. In all these areas students in the new program did as well or better than those in the traditional curriculum.

Frontiers in Education (FIE) Conference

作者： C.D. Pionke F.E. Weber J.R. Parsons J.E. Seat D.C. Yoder The Engineering Fundamentals engage Program University of Tennessee Knoxville TN USA

A strategy has been developed at the University of Tennessee (UT) to ensure that all freshmen engineering students develop and demonstrate competency in a minimum set of engineering computer skills. This strategy is a key component of the integrated engage program developed at UT over the past two years. The strategy is twofold. First, the computer skills are directly connected to the material being taught in other parts of the course. The idea is that as the student learns a particular computer skill, they can immediately apply it to solve problems assigned in other parts of the integrated engage program. Second, the manner in which the skills are assessed ensure mastery. The student must pass a set of "proficiency exams" that cover all aspects of the computer skills. These exams measure the minimum skills that are deemed necessary for success and a student must pass all proficiency exams by the end of the semester in order to pass the course. This paper provides the details of the engage strategy including a discussion of the integrated material as well as the logistics of the proficiency exams' development and administration. Preliminary results from a pilot program conducted in the 1997-98 academic year, and the current transition program being conducted in the 1998-99 academic year indicate that the strategy is successful.

MULTIPLE STATES OF A VISCOUS FREE SURFACE FLOW: TRANSITION FROM PRE-METERED TO A METERING INFLOW

引用

International Journal for Numerical Methods in Fluids 1998年第9期24卷

作者： M. S. Carvalho L. E. Scriven Coating Process Fundamentals Program Center for Interfacial Engineering and Department of Chemical Engineering and Material Science University of Minnesota Minneapolis MN 55455 U.S.A.

In a forward-roll coating gap or nip, steady laminar flow of liquid between counter-rotating cylinders or rolls is used to split the flow into a coated layer on one roll and a rejected layer on the other. Both layers have free surfaces in contact with air. Liquid may be carried into the gap as a layer on one or both rolls. If the arriving layer is not too thick, all of the liquid flows through the gap, a situation called pre-metered . If the arriving layer is too thick, part of the liquid is rejected and runs back down the lower roll. The flow rate through the gap is said to be metered and is not known a priori . The transition from a pre-metered regime to the metered situation was examined by solving the Navier–Stokes system for steady, two-dimensional flow in a domain bounded by free surfaces, two rigid roll surfaces and chosen inflow and outflow surfaces. The free boundary condition , as described by Papanastasiou et al. ( Int. j. numer methods fluids , 14 , 587 (1992)), was explored and proved to accommodate both the pre-metered and metered regimes. A run-back flow state across the synthetic inlet plane was obtained, provided a condition on the thickness of the arriving layer was replaced by a kinematic condition at a certain stage. The coupled equation system was solved by Galerkin's method with finite element basis functions. The resulting non-linear algebraic system was solved by Newton's method with initialization by pseduo-arc-length continuation and automatic parameter step adjustment. Results show the existence of multiple solutions which can lead to hysteresis. Flow regime maps were constructed to portray the operating parameter range in which a coating bead can exist and the ranges in which a coating gap operates in either the pre-metered or the metering regime. © 1997 by John Wiley & Sons, Ltd.

ELASTOHYDRODYNAMICS OF BLADE COATING

引用

AICHE JOURNAL 1990年第4期36卷 587-597页

作者： PRANCKH, FR SCRIVEN, LE Coating Process Fundamentals Program Department of Chemical Engineering & Materials Science University of Minnesota Minneapolis MN 55455

Blade coating is the most common method of coating paper, and it is applied in coating magnetic suspensions and adhesives. Typically, the blade's upstream edge is clamped into a rigid holder so that the blade and substrate form a converging wedge. The translating substrate drags liquid into the wedge, where liquid forces develop and deflect the elastic blade, but it is loaded externally to counteract the deflection. Liquid dragged past the blade and thus the coating thickness depend on the elastohydrodynamic interaction among blade, liquid, and loading. Shell theory and lubrication flow theory describe the interaction by means of differential equations that are shown to be equivalent to Saita and Scriven's (1985) earlier formulation but that lead to a computationally more efficient analysis. Predictions computed agree with those of the earlier formulation and with experiments. Moreover, the new predictions illustrate effects of normal force loading and broaden the theory of blade coating.

He was employed by D.B. Cargo Line (Turkey) as an engineering officer on ocean-going cargo vessels from 1971 to 1973. After receiving his masters degree in power engineering in 1975 he was employed by J.J. Henry Co. Inc. in Washington DC where he was involved in supporting the DTNSRDC Shipboard Energy Conservation Program which included the development of the steam system simulation (STMSYS) heat balance computer program for FF-1052/1078 class frigates. In addition he was cognizant engineer for various fluid systems designs for PCG and CSGN. In 1978 he joined M. Rosenblatt & Sons Inc. where he was cognizant engineer for various fluid systems designs for CVV DDG-51 and ARS-50. He was also leading engineer in support of DTNSRDC for the development of innovative machinery options for the baseline DD-963. In 1980 he joined NKF Engineering Inc. where he directs and performs DTNSRDC ship energy conservation analyses for frigates cruisers destroyers and aircraft carriers.

The shipboard energy conservation assist team (SECAT) program was introduced to the US Pacific Surface Fleet (SURFPAC) in 1983 following one year testing in the US Atlantic Surface Fleet (SURFLANT). Experiences aboard SURFLANT ships had provided the basis for improvements which could also be applied to SURFPAC ships. Chief among these improvements were simple fuel measurement, fuel curve development methods, an energy survey checklist, and an equipment status board which identifies economic machinery alignments. The first SURFPAC ship to receive a SECAT visit was a FF-1052 class ship. Fuel consumption was significantly higher on this ship than the six FF-1052/1078 class SURFLANT ships previously visited. SECAT immediately looked for reasons for this increase in fuel consumption. Three significant changes received by this ship and not received by the six SURFLANT ships were identified. They were a new design economizer, Navjet vice Wallsend burners, and removal of overload control valves on the forced draft blowers. Another SURFPAC frigate with the same three changes was visited to validate the results obtained from the first ship. This paper discusses recent improvements to the SECAT program. It also examines the differences in fuel consumption observed between SURFLANT and SURFPAC FF-1052/1078 class ships. The economics of potential solutions to the higher fuel consumption problem aboard SURFPAC ships is analyzed with special emphasis on alternative burner designs and forced draft blower changes. Recommendations are made to reduce fuel consumption both by equipment changes and expanded energy initiatives.

Synthetic fuels are assessed with respect to their potential use aboard Navy ships. The status of petroleum resources and the development of fuels from shale, coal, and biomass is summarized. A scenario of the projected availability of these fuels is presented which shows the sensitivity to funding and schedule. Diesel engine and gas turbine combustor tests with small quantities of coal derived and shale derived fuels are described and these tests results are evaluated for shipboard applications. Special shipboard modifications are discussed such as the replacement of rubber base seals, gaskets, and hoses with viton and teflon, and the use of stainless steel piping because of the fuel characteristics. Considerations for dual fuel systems using Diesel Fuel Marine for starting, stopping, and maneuvering are included based upon early test results. Consideration is given to the use of these fuels in the shipboard environment since they require special handling and adoption of personnel safety measures.
