In the present work, the influence of intrinsic angular momentum on transport coefficients in a single-component gas flow is studied on the basis of the generalized Chapman–Enskog method. A self-consistent set of flow equations is derived, both for an inviscid and viscous flow approximations. It is shown that when angular momentum is considered, the shear viscosity coefficient is a tensor of rank 4, the thermal conductivity coefficient is a tensor of rank 2. The presence of cross-coupling between the heat flux and flux of angular momentum is also demonstrated. Numerical results for the thermal conductivity coefficient, coefficient of coupling between angular momentum and heat fluxes, as well as the bulk viscosity are presented for the case of 2-dimensional flow of atomic hydrogen.

在目前的工作中，基于广义Chapman–Enskog方法研究了固有角动量对单组分气流中传输系数的影响。对于不粘稠的和粘性的流动近似，导出了一组自洽的流动方程。结果表明，当考虑角动量时，剪切粘度系数为等级4的张量，导热系数为等级2的张量。还证明了热通量和角动量通量之间存在交叉耦合。 。对于二维氢原子流，给出了导热系数，角动量与热通量之间的耦合系数以及体积粘度的数值结果。
