本文描述了一种在数值求解有限体无界粘性可压缩流问题时，将非局部人工边界条件设置在计算区域外边界的算法。我们的技术是基于广义Calderon投影算子的使用和差势法的应用。给出了一些计算结果。
In this paper we describe an algorithm for the nonlocal artificial boundary conditions setting at the external boundary of a computational domain while numerically solving unbounded viscous compressible flow problems past the finite bodies. Our technique is based on the usage of generalized Calderon projection operators and the application of the difference potentials method. Some computational results are presented.
