Homogeneous mixture models are widely used to predict the hydrodynamic cavitation. In this study, the constant-transfer coefficient model is implemented into a homogeneous cavitation model to predict the heat and mass diffusion. Modifications are made to the average bubble temperature and the Peclet number for thermal diffusivity in the constant-transfer coefficient model. The evolutions of a spherical bubble triggered by negative pressure pulse are simulated to evaluate the prediction of heat and mass diffusion by the homogeneous model. The evolutions of three bubbles inside a rectangular tube are simulated, which show good accuracy of the homogeneous model for multibubbles in stationary liquid.

考虑均质混合模型中空化的扩散效应

均质混合物模型被广泛用于预测流体动力空化。在这项研究中，将恒定传递系数模型实现为均相空化模型，以预测热量和质量扩散。在恒定传递系数模型中，对平均气泡温度和热扩散的Peclet数进行了修改。模拟了由负压脉冲触发的球形气泡的演化，以评估均质模型对热量和质量扩散的预测。模拟了矩形管内三个气泡的演化，显示了固定液体中多气泡均质模型的良好准确性。
