The self-consistent simulation of transport and turbulence in tokamak edge plasma on the EAST tokamak is performed by coupling the fluid plasma/neutral 2D transport code SOLPS-ITER and the fluid 3D turbulence code BOUT++. The convergence of the coupling is validated. The changing rates between the two consecutive profiles of density, electron temperature and ion temperature are close to zero in the last several iteration steps, and the variations of the transport coefficients D r , χ e and χ i also show the tendency to diminish as the iteration step increases, indicating that the coupling tends to be in a quasi-steady state. The edge plasma at the time t = 3400 ms in shot 36 780 with deuterium discharge on EAST is simulated by the SOLPS-ITER/BOUT++ coupling. The MHD equilibrium at the shot time with the lower single-null configuration is used for the production of the computational meshes for ...

使用SOLPS-ITER / BOUT ++耦合模拟EAST边缘等离子体

通过耦合流体等离子体/中性2D传输代码SOLPS-ITER和流体3D湍流代码BOUT ++，可以对EAST托卡马克上的托卡马克边缘等离子体中的传输和湍流进行自洽模拟。耦合的收敛性得到验证。在最后几个迭代步骤中，两个连续的密度，电子温度和离子温度曲线之间的变化率接近于零，并且随着系数的增加，传输系数D r，χe和χi的变化也呈现出减小的趋势。迭代步长增加，表明耦合趋于处于准稳态。通过SOLPS-ITER / BOUT ++耦合模拟了在EAST上具有氘气排放的36 780次t = 3400 ms时的边缘等离子体。
