摘要
在给定的边界条件及评价方法下,利用CFD软件AVL-FIRE对发动机气缸内流场的涡流和气流速度进行数值模拟,分析不同气门升程下缸内涡流和气流速度状况,借助流量系数和涡流比的试验结果,验证了数值模拟结果具有可信度.
Under the given boundary conditions and evaluation methods, this paper used three-dimensional software AVL-FIRE to simulate the engine in cylinder flow field of swirl and airflow velocity, and analyzed cylinder swirl and velocity conditons under different valve lifts. With flow confficients and swirl ration test results, the numerical simulation result shows good reliability.
