采用压力修正法 (SIMPLE法 )和混合 H- D格式 ,结合 K-ε湍流模型 ,求解加权平均 N- S方程 ,数值模拟了对转式轴流通风机内的流场 ,设计性能良好的对转风机有较好的流场 ,说明通过求解 N- S方程是定性分析对转式风机性能的一种有效方法
The pressure-corrected method (SIMPLE method) and hybrid H-D format were used in combination with the K-ε turbulence model to solve the weighted average N-S equation. The numerical simulation of the flow field in a rotary axial fan with good design performance Turbine has a better flow field, indicating that by solving the N-S equation is a qualitative analysis of the performance of a rotating fan is an effective method
