【摘要】 <正> 一、粘性项的展开式 1.粘性力 由于粘性力f等于单位质量流体的粘性应力张量的散度,所以利用克里斯托夫符号Γ_αβ^γ与度量张量分量之关系,此式可改写为 另一方面,从粘性应力张量Π的定义式可知更多还原

【Abstract】 The expansions of viscous terms in the basic aerodynamic equations in a non-orthogonal curvilinear coordinate are derived for the compressible flow with a variable coefficient of viscosity. These expansions in the matrix form are convenient for designing programs of calculations. The method of numerical differentiation for the expansions obtained in, this paper is introduced shortly.更多还原
