Pool boiling heat transfer compared to single-phase heat transfer has a higher heat transfer capacity due to the use of latent heat evaporation of liquids. Therefore, in this study, the pool boiling heat transfer on a flat vertical plate and plate with triangular and circular grooves have been investigated using numerical simulations. In studies, the effect of adding two types of triangular grooves, two types of circular grooves with different dimensions, and four heating surface temperatures has been investigated. In order to simulate the two-phase flow in this study, the volume of the fluid method was used and the governing equations were solved using the finite volume method. The obtained results showed that adding triangular and circular grooves on the heating surface will increase the average heat flux. In the triangular grooved surface case, the average heat flux which entered liquid increased from 128% to 177%. By using a circular groove, the average heat flux augments about 69% to 105%.  Also, the water vapor value in the triangular grooved surface case increased from 160% to 340%, and in the circular grooved surface case rises 101% to 155%.
