Wave heating is an important way to implement the controlled fusion. The propagation and absorbability of wave in the plasma are described by the two-fluid equations and Maxwell’s equations. A numerical algorithm based on the FDTD method and the MacCormack scheme is designed. The numerical simulation based on parallel computing is carried out to verify the validity of the algorithm and simulation.

Abstract This paper discusses the fabrication and the characterization of a MEMS-based micromixer. Active perturbations provided by a pressure source/sink system are used to enhance the mixing between two fluid streams. From our preliminary test, it appears that an effective mixing is possible through the generation of chaotic-like distortions at the interface between two streams. A numerical simulation based on a kinematical model reveals a similar behavior under the same condition.

Good Agreement

The thixo-forging of magnesium matrix composite was analyzed with computer numerical simulation based on rigid viscoplastic finite element method. The constitutive model of SiCp/AZ61 composite was established in our prior literature. Behavior of metal flow and temperature field were obtained. The differences between traditional forging and thixo-forging processes were analyzed. Results indicated that thixo-forging was better in filling cavity than forging. Simulation results were good agreement with experimental ones.
