Dynamic Modeling And Simulation Of A Multi Effect Humidification-Dehumidification Desalination Unit, Mohammed I. Sohel, B Dawoud
Dynamic Modeling And Simulation Of A Multi Effect Humidification-Dehumidification Desalination Unit, Mohammed I. Sohel, B Dawoud
Faculty of Engineering and Information Sciences - Papers: Part A
Recently solar distillation using Multi Effect Humidification-dehumidification (MEH) cycle is receiving special attention. In this communication detailed models of MEH are presented that take into account most of the dynamic behavior with reasonable accuracy. Using these models simulation was carried out and the results of simulation were discussed in this paper. To find out the competence of the newly developed models, some of the simulation results were compared with the available experimental data in the literature. It turned out that the result of simulation give a very good agreement with the experimental data. The maximum deviation between simulation and experimental …

Finite Element Modeling Of Contact Interface Between Trans-Tibial Residual Limb And Prosthetic Socket, Winson Lee, Ming Zhang, Xiaohong Jia, Jason Cheung
Faculty of Engineering and Information Sciences - Papers: Part A
Finite element method has been identified as a useful tool to understand the load transfer mechanics between a residual limb and its prosthetic socket. This paper proposed a new practical approach in modeling the contact interface with consideration of the friction/slip conditions and pre-stresses applied on the limb within a rectified socket. The residual limb and socket were modeled as two separate structures and their interactions were simulated using automated contact methods. Some regions of the limb penetrated into the socket because of socket modification. In the first step of the simulation, the penetrated limb surface was moved onto the …
