高背压下燃油喷雾倾斜碰壁数值模拟

Numerical Modelling for Fuel Spray Impinging on Inclined Flat Wall under High Environment Pressure

利用三维燃油喷雾碰壁模型，对日本学者国吉光等人所做的高背压下喷雾倾斜碰壁实验进行了模拟计算，结果表明，两者较吻合。并发现在高背压下喷雾倾斜碰壁所形成的油膜形状并不像常规理论所认为的长叶形，而是扇形。

The Spray impinging on inclined flat Wall in high emviroment pressure is calculated using a 3 - D model. Results obtained agree with the experimental data of kuniyoshi et al, and it is found that the fuel film shape generated by spray impingement is of sector, not like a long-leaf considered as usual.
