Due to the important role critical heat flux (CHF) plays in the boiling field, it is of great significance to study CHF, especially the mechanism of CHF in the nucleate boiling. In this study, a new numerical model to predict CHF was proposed base on the Monte Carlo method. This model can take into account of the bubble generation, bubble growth, bubble sliding and bubble departure. The results showed good agreement with the experimental results. Further works are needed to apply this model to a wider range of experiments and other working conditions.
