研究对应于电子压、离子压、光子压的扰动隅角力的计算方法,提出二维三温辐射流体力学拉氏计算中的两种子网格压力方法,即基于状态方程和基于几何的方法.数值试验表明,这两种方法均能很好地抑制二维三温辐射流体力学拉氏计算中出现的网格非物理畸变.
Computing methods for perturbation corner forces in electron pressure,ion pressure and photon pressure are investigated.We propose two kinds of subzonal pressure method for Lagrangian algorithm of two-dimensional three-temperature radiation hydrodynamics.Numerical tests show that both methods work well in eliminating unphysical deformation of Lagrangian mesh.
