This article proceeds a new method which can continuously prepare emulsion by using a venturi tube, to achieve the goal of emulsify diesel oil, methane and water. The diesel oil comes in at the entrance of the venturi tube. The solution of methane and water comes in at the throat of venturi tube and mixes with diesel oil to form emulsion. The preparation system is designed and the structure parameter of the venturi tube is calculated. Then FLUENT is used to do a series of numerical simulation of the flow in the venturi tube under different parameters of spread angle and ratio of length to diameter, thus deciding the best parameters which are 8 degree and 1.25. The basic data for the design of experimental system is provided.

The paper presents a method for monitoring CO 2 leakage in geological carbon dioxide sequestration. The unsteady state dispersion of leakage CO 2 from geosequestration simulation results showed that the ensemble trend of elevated concentration caused by CO 2 leakage can be viewed as a concentration step change perturbation to the background variation and the initial stage of dispersion process is an increasing variation. The correlation between O 2 and CO 2 variation is well linear if there is no leakage. The external linear perturbation decreases the correlation coefficient. Moreover, too large step change concentration will also reduce the average correlation coefficient. Therefore, online correlation analysis between O 2 and CO 2 in atmosphere is useful to distinguish the leakage CO 2 from complex background variation especially at the beginning of leakage occurring.
Ignition delay times of n-butanol/oxygen diluted with argon were measured behind reflected shock waves. Experiments were carried out in the temperature range 1200-1650 K, at 2 and 10 atm, and at equivalence ratios of ...
