Beschreibung:
In reality, the mass transfer and heat transfer of particles in solid materials interact with each other. The influence of uneven temperature spatial field on mass transfer is called Soret effect, and the influence of uneven concentration spatial field on heat transfer is called Dufour effect. Due to the plasma particle flow and ion temperature change drastically in a sawtooth shape during the discharge of the Tokamak device, the Soret and Dufour effects will have a more obvious influence on the mutual diffusion of deuterium concentration and temperature.The JD-CF program was used to calculate the HL-2A divertor target plate RAFM steel and tungsten materials. The results show that considering the Soret and Dufour effects with the constraints of the L mode and H mode will have a certain depth of influence on the concentration and temperature distribution of deuterium. The depth of influence of Soret and Dufour effects with the constraint of H mode is deeper than that of L mode, and the depth of influence on RAFM steel is deeper than that of tungsten. The influence of Soret and Dufour effects on deuterium concentration and temperature is applied to the materials of fusion device discharge experiments, this is an innovative simulation study
