Abstract Flow pattern and heat transfer of flow boiling for different flow orientation, mini-channel width and height were presented in this work. The data were obtained by the numerical simulation with the coolant of R141b flow in a vertical mini-channel. Orientation includes upward and downward. A constant heat flux was loaded at the wall of the channel, of which the width ranges from 1 mm to 3 mm, and a length changes from 200 mm to 400 mm. Subsequently the impact of those parameters that referred to heat flux, inlet temperature and inlet temperature of the coolant could be investigated by carrying out the numerical calculation. In addition, a validation for the model was illustrated in comparison with the previously experimental data.

微通道内流动沸腾流型及传热特性的数值分析

摘要 本文介绍了不同流动方向、微通道宽度和高度下流动沸腾的流动模式和传热。数据是通过R141b冷却剂在垂直微通道中流动的数值模拟获得的。方向包括向上和向下。在通道壁上加载恒定的热通量，其宽度范围为 1 mm 至 3 mm，长度范围为 200 mm 至 400 mm。随后，可以通过数值计算来研究这些参数的影响，这些参数涉及冷却剂的热通量、入口温度和入口温度。此外，与之前的实验数据相比，还说明了对模型的验证。
