The two-fluid Eulerian model, coupled with the heat flux partitioning model, is being widely used to predict subcooled flow boiling characteristics and critical heat flux (CHF). The heat flux partitioning model relies on essential parameters like bubble departure diameter, departure frequency, and nucleation site density. Mainly, performing experiments to determine bubble departure diameters and frequencies is challenging. Another approach is to use semi-mechanistic models; however, even such models rely on some crucial parameters like advancing contact angle, receding contact angle, contact diameter, and many others. In this study, the influence of such parameters, and the role of different forces in determining bubble departure diameters and departure frequencies, at high-pressure conditions is studied. Moreover, a parametric analysis is carried to understand the influence of such parameters on CHF prediction.

双流体欧拉模型与热通量分配模型结合在一起，已广泛用于预测过冷流沸腾特性和临界热通量（CHF）。热通量分配模型依赖于基本参数，例如气泡离开直径，离开频率和成核位置密度。主要地，进行实验以确定气泡离开的直径和频率是具有挑战性的。另一种方法是使用半机械模型。但是，即使这样的模型也依赖于一些关键参数，例如前进接触角，后退接触角，接触直径等。在这项研究中，研究了这些参数的影响以及在高压条件下不同力在确定气泡离开直径和离开频率方面的作用。此外，
