摘要
阐述了用分形耦合贴体网格坐标和流体有限控制容积法，求解具有多分支、变曲率和变截面的复杂几何形状和边界条件的柴油机模件式脉冲转换系统中的非定常粘性可压三维流动计算问题，编制了计算程序进行计算．计算结果表明，这种计算方法对柴油机模件式脉冲转换系统的流动计算是相当有效的．其计算程序不仅可用于柴油机模件式脉冲转换系统，亦可用于脉冲系统和定压系统的流动计算，具有一定的通用性．
A theoretical and practical approach to the
calculation of nonstationary viscous and compressible 3 D flow in the modular pulse converter
turbocharging system of a diesel engine are described. The fractional coupled body fitting grid
coordinate and the finite control volume method in fluid are used in the calculation. The
geometric configuration and the boundary conditions are complicated in the cases of multiple
manifolds, variable curvature and variable structure. A computing program is compiled and a
practical example is computed. The results of calculation show that the method proposed is
useful.
