One of the challenging issues in the evaporation process is investigating the dynamic behavior of bubbles while considering the continuous changes in the bubble's contact angle with the surface. In this study, the effect of the dynamic contact angle on the accuracy of predicting the heat transfer coefficient and the dynamic behavior of the bubble during the evaporation process is examined. In this numerical study, the Volume of Fluid (VOF) method was used to track the two-phase interface, and the Lee phase change model was employed to simulate the liquid-to-vapor phase transition. The influence of the dynamic contact angle on the prediction accuracy of the heat transfer coefficient and the bubble's geometric parameters was analyzed. Furthermore, the effects of wettability, heat flux, bubble diameter, and bubble contact diameter on the heat transfer coefficient and the bubble departure time were investigated. A comparison of the heat transfer coefficient results with the Stephan and Preußer correlation revealed that the predicted heat transfer coefficient in the dynamic contact angle case is approximately 37% higher than in the constant contact angle case, with a 1.4% error compared to the Stephan and Preußer correlation. Moreover, in the dynamic contact angle case, the bubble's geometric parameters during evaporation were predicted with an error of less than 4% compared to experimental results. The results also indicated that surface wettability has a significant impact on the heat transfer coefficient. Finally, it was shown that increasing the heat flux, decreasing the bubble diameter, and reducing the bubble base diameter significantly enhance the heat transfer coefficient and decrease the bubble departure time.
