多缸内燃机进气系统流动计算的分块结构化网格设计

The Design of Block-structured Grid in Inlet System Flow Calculation of Mulyi-cylinder Internal Combustion Engine

本文阐述多缸内燃机进气系统分块结构化网格生成的方法，并应用这一方法按照多维流动计算的要求对某一六缸柴油机进气系统进行了贴体分块结构化网格设计计算。其结果表明，该方法不仅适用于结构形状复杂的多缸内燃机进气系统，而且可推广于其它结构形状复杂的流场。

This paper describes the method of block - structured grid generation in inlet system of multi - cylinder internal combustion engine. Using this method, the calculation is performed for the body - fitted block - structured grid design in the inlet system of a six - cylinder diesel engine according to the requires of multi - dimensional flow calculation. The result shows that this method can be used for flow calculation in complex structures.
