Physical and chemical processes in the Urea-SCR system are simulated by using computational fluid dynamics CFD and chemical kinetics methods. The best location of nozzle and the suitable number of nozzle holes have been held through the analysis of the simulation results, which provides a reference about the optimal design for the catalytic converters.
The structure was introduced, status of parallel-type Electrostatic Fabric Filter were researched, and the factors influencing collection efficiency were analyzed in the paper. With software of Gambit which also meshed the calculating region, Three-dimensional structure model of the precipitator was established. And then the numerical simulation of the air distribution characteristic was carried on...
Computational fluid simulations were developed for a generic blood-interfacing implantable device. The simulations were analyzed to determine hemodynamic behavior within the device, including velocity profiles, the magnitude of shear stress, and pressure drop. By monitoring 100 streamlines, the total blood damage induced by the device was estimated and compared to that observed for a bioprosthetic...
