It emphasizes the phasechange and thermal chemistry of particles and includes some other effects such as flow turbulence, gascompressibility and temperature-dependence of the transport properties under the plasma condition.Example calculations for plasma-dissociated zircon process indicate the influences of reactor operationparameters on the plasma jet and particle behavior.展开更多

One possible application of this model is to provide a source term originating from neutral transport calculation for any other edge plasma transport code, for instance, B-2 code, which has been used to simulate edge plasma transport of the HL-2A divertor configuration. Especially it can be utilized to quickly classify the plasma in divertor region as high or low recycling regime.展开更多
