气泡生长速率的预测对于建立精确的气泡偏离直径模型和计算有核沸腾过程中的传热速率是非常重要的。本文利用去离子水在纯铜表面饱和沸腾时的气泡生长实验数据，对现有的均相和非均相气泡生长模型进行了评价研究。实验分别在压力为1,0.5和0.15 bar，过温范围为5.1 - 19.5 K的条件下进行。首先，本文对均相和非均相沸腾中的气泡生长模型进行了评述。发现均匀生长模型在某些条件下与实验数据有一定的一致性，因此在非均相沸腾中应谨慎使用。在假设气泡生长是由于气泡周围过热边界层的蒸发引起的基础上提出的一些模型之间有很好的一致性。仅基于微层蒸发的模型不能解释实验数据，即在某些条件下部分吻合。在所有条件下都能很好地预测数据的模型是Van Stralen b[25]的“松弛边界层”模型。本文对该模型进行了推广，提出了两个新的出发直径和出发时间的经验模型。
Prediction of bubble growth rate is very important for the development of accurate models for bubble departure diameter and thus the heat transfer rates in nucleate boiling. This paper presents an evaluation study to the existing homogeneous and heterogeneous bubble growth models using our experimental data for bubble growth in saturated pool boiling of deionized water on a plain copper surface. The experiments were conducted at pressures 1, 0.5 and 0.15 bar and superheat in the range 5.1 – 19.5 K. To start with, the paper presents a critical review on bubble growth models in homogeneous and heterogeneous boiling. It was found that homogeneous growth models achieved some partial agreement with the experimental data at some conditions and thus they should be used carefully in heterogeneous boiling. There was a good agreement between some of the models that were suggested based on the assumption that bubble growth occurs due to evaporation from the superheated boundary layer around the bubble. The models based on microlayer evaporation only could not explain the experimental data, i.e. partial agreement at some conditions. The model that predicted the data very well at all conditions was the “relaxation boundary layer” model by Van Stralen [25]. This model was generalized in the current study by suggesting two new empirical models for the departure diameter and departure time.
