摘要:

采用高密度等离子体电子传导模型,计算出了一整套适用于模拟强磁场下任意混合材料中局部电离和局部简并的等离子体中的输运参数,获得的参数在很宽的等离子体温度和密度范围内有合理的精度,可广泛应用于Z箍缩等离子体、激光聚变和磁约束聚变的模拟。

关键词: 等离子体, 输运参数, Fermi-Dirac积分

Abstract:

An electron conductivity model for dense plasma is utilized to calculate a complete set of transport coefficients in plasma. These coefficients, applying to partially ionized and partially degenerated plasmas with arbitrary compositions, are reasonably accurate in a wide range of plasma temperature and density. They can be used in the simulations of magnetic confinement fusion, laser fusion, and Z-pinch plasma, etc.

Key words: Plasma, Transport coefficient, Fermi-Dirac integral
