Abstract Due to the important role critical heat flux (CHF) plays in the nucleate boiling field, it is of great significance to study CHF, especially the mechanism of boiling crisis occurrence. In this study, an extended numerical model to predict CHF for flow boiling was proposed based on the Monte Carlo method. This model considers of the bubble generation, bubble growth and bubble departure. CHF was assumed based on the percolative nature of bubble interactions. Numerical simulation results showed good agreement with the experimental results, which demonstrated that this model was able to be used to predict CHF. Further works are needed to apply this model to a wider range of experiments and other working conditions.

一种预测流动沸腾沸腾危机的气泡渗透方法的扩展开发

摘要 由于临界热通量（CHF）在核沸腾场中的重要作用，研究CHF，尤其是沸腾危机发生机制具有重要意义。在这项研究中，基于蒙特卡洛方法提出了一种用于预测流动沸腾 CHF 的扩展数值模型。该模型考虑了泡沫的产生、泡沫的增长和泡沫的离开。CHF 是基于气泡相互作用的渗透性质假设的。数值模拟结果与实验结果吻合良好，表明该模型能够用于预测CHF。需要进一步的工作将该模型应用于更广泛的实验和其他工作条件。
