| 摘 要： | 应用Realizable k-ε湍流模型和Mixture两相流模型,对电子膨胀阀小开度下的二维流场进行了数值模拟,根据计算结果,使用宽频噪声计算方法得到了膨胀阀内流体噪声分布。对电子膨胀阀的改进模型进行了数值模拟,并对流体的速度场及其噪声辐射结果进行了分析,结果表明,阀口长度加长和阀口改为喇叭口结构可以减小射流噪声。

| Abstract: | Numerical simulation of two-dimensional flow field was carried out for electronic expansion valve with Realizable k-ε turbulent model and mixture two-phase flow model. Based on the calculation result, flow noise distribution in the expansion valve was gained with broadband noise calculation method. Numerical simulation of the improved model of the electronic expansion valve was conducted. Besides, velocity field of the flow and noise radiation results were analyzed. The results show longer valve port and trumpet structure of the valve port can reduce jet noise. |
