The computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. The program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area S = 1 m × 1 m = 1 m2, cell pair number N = 300 pairs). The stack operatingconditions are optimized. Seaw...

modeling the heat and mass transport in micro channel is being used extensively in researches and industrial applications. the aim is optimizing fuel cell designs before building a prototype for engineering application. in this study, numerical, three-dimensional, single phase computational fluid dynamics model of a proton exchange membrane fuel cell with both the gas distribution flow channels...

Electromigration is a major road block in the pursuit of further miniaturized electronics. In the next generation micro and sub micro electronics current density is expected to exceed 10 A/cm. In this paper an electromigration induced strain-current density model is proposed and implemented in finite element procedure for solution of boundary/initial value electromigration problems. Numerical s...

A process analogous to electromagnetically induced transparency in atoms is described for an ideal plasma. Two electromagnetic fields whose frequency difference is near, but not equal, to the plasma frequency will drive a longitudinal plasma oscillation whose contribution to the current density opposes the current density produced by either field, if alone. This creates a passband at frequencie...

in this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. the influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final ph and energy consumption rate was determined. dye removal was increased with increases in solution ph, current density and contact tim...

in this study, different methods of separating of the microalgae from the culture medium as one of the most important and expensive steps in achieving commercial production of biodiesel from microalgae was investigated. electro coagulation-flotation (ecf) was preferred among these methods due to its process simplicity and capability to scale up. the effect of three parameters, i.e., initial ph,...
