摘　　要：为预测水平矩形小尺度通道内气泡脱离直径,以研究其泡核沸腾传热特性,采用力学方法对加热壁面附壁气泡进行力学分析,构建了一种基于受力平衡的气泡脱离直径预测模型。采用可视化实验的方法对其进行验证,结果表明,模型预测结果与实验数据之间的平均相对误差为±13.52%,该模型具有良好的气泡脱离直径预测准确度。In order to predict the bubble departure diameter in a horizontal rectangle heating mini-channel to study its heat transfer characteristics, a bubble departure diameter predicting model based on force balance is proposed. A visualization experiment is used to verify it, and the results show that the average relative error between the prediction result and the experimental data is 13.52%, the predicting accuracy of bubble departure diameter model is good.
