International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)

作者： Chao Liu Kejun Wang Qian Wang School of Mechanical and Electric Engineering Soochow University Suzhou China Jiangsu Provincial Key Laboratory of Advanced Robotics Soochow University Suzhou China

Beetle hindwings have two specific features: the deployable hindwing and corrugation wing. In the low Reynolds numbers environment, the corrugated wing structure of insect wings proves to be essential for improving *** order to explore further whether flexible corrugated structure has a significant effect on aerodynamic effects. Two 3D corrugated wing models (3D-CW models) were designed with rigid and flexible properties, respectively. In this paper, based on ANSYS Fluent, the fluid-structure interaction method is used to solve the Navier-Stokes equations numerically. At a series of angles of attack, the flexible wing has better aerodynamics at angles of attack larger than 10°; the deformed leading edge can induce a stronger Leading edge vortex (LEV) than found at the rigid wing.

Flexible strain sensors play a critical role in wearable human-machine interaction (HMI), allowing for natural and intuitive communication between humans and machines. Conductive hydrogels are promising candidates for flexible sensor materials due to their flexibility, sensitivity, and biocompatibility. However, the conventional hydrogels tend to freeze at subzero temperatures or lose water at room temperature, resulting in decreased electrical conductivity and mechanical flexibility, and thus poor long-term stability. Herein, a multifunctional MXene/polyacrylic acid (PAA) organohydrogel with high toughness and self-healing, self-adhesive, antifreeze, and long-term moisturizing ability was prepared using a facile solvent replacement method. It has a high sensitivity (gauge factor ∼10.96), wide detection range (0-1304%), and stable signal output for 500 cycles, making it an ideal flexible strain sensor for monitoring human joint movements, subtle expression changes, and pronunciation in real time. This work provides a new paradigm for wearable artificial intelligence and human-machine interactions in complex environments. © 2023 RSC.

作者： Yu, Azhi Ye, Qing Li, Jinlong Li, Xinhao Wang, Yao Rui, Qingqing Jiangsu Key Laboratory of Advanced Catalytic Materials and Technology School of Petrochemical Engineering Changzhou University Jiangsu Changzhou213164 China

This work presents an approach for the recovery of high purity cyclohexane (CYCLO) and tertiary butanol alcohol (TBA) from wastewater. After thermodynamic analysis, a heterogeneous azeotropic pressure swing distillation process (HAPSD) with a natural liquid-liquid decanter is proposed. The heterogenous-azeotrope distillation with a high-pressure column and a dividing-wall column process (HADWC) is also being developed to propose a green and sustainable process. Those processes are optimized by simulated annealing algorithm by linking Aspen Plus and MATLAB via taking the minimization of TAC as objective function. Three energy-efficient HADWC processes are proposed based on the process intensification approach of heat pump and heat integration technologies. All processes are evaluated for multi-criteria performance including economy, energy consumption, gas emissions and thermodynamic efficiency. As the result, HADWC-HP-HI process shows the best performance with 30.56%, 52.59%, 50.69%, and 57.94% reducing over the conventional HAPSD process in terms of economy, energy consumption, gas emissions and thermodynamic efficiency, respectively. © 2023, The Authors.

Investigation Of Side-Stream Extractive Distillation for Separating Multi-Azeotropes Mixture Based on Multi-Objective Optimization

SSRN

引用

SSRN 2023年

作者： Xu, Zhixia Ye, Qing Ding, Yan Li, Jinlong Wu, Hanbin Pan, Jing Jiangsu Key Laboratory of Advanced Catalytic Materials and Technology School of Petrochemical Engineering Changzhou University Jiangsu Changzhou213164 China

In this paper, a conventional triple-column extractive distillation process and three side-stream extractive distillation processes are investigated for separating a ternary mixture of n-hexane/ethyl acetate/acetonitrile. A multi-objective genetic optimization method is applied to optimize the four processes with the minimum total annual cost (TAC) and entropy production as two objective functions. The results indicate that three side-stream extractive distillation processes can effectively reduce the remixing phenomenon, achieving a reduction in economy and energy consumption as well as increase the thermodynamic efficiency. Among the processes, the single side-stream extractive distillation process presents optimal performance considering economy, energy-efficient and thermodynamic efficiency. Specifically, it can reduce 6.17% of TAC, 7.85% of energy consumption and 15.54% of entropy production in comparison to the triple-column extractive distillation process, respectively. © 2023, The Authors.
