| Abstract: | The modeling algorithm and calculating examples of the three-dimensional steady compressible flow simulation in the intake port of automotive engine are presented. In order to realize the quantitative analysis and be used in practical design, a new mesh generating method is proposed, a computing software is developed, and the measures for increasing accuracy and accelerating convergence are investigated. |
