Boiling heat transfer always has been proposed as a solution for enhancing heat transfer between the fluid and solid surfaces. Subcooled flow boiling is one of the mechanisms that occur in Internal Combustion Engine water jacket in which high amounts of heat is transferred. In this research, it has been tried to simulate subcooled flow boiling in a geometry similar to coolant channel inside the internal combustion engine using commercial software. The geometry, based on experimental studies, was considered as a channel with a rectangular cross-section and a hot spot on the channel lower surface, this geometry is the innovative part of this study. The models required for simulating the subcooled flow boiling were extracted from literature and implemented in the commercial software. The obtained results, after validation, applied in the final geometry. The results showed that with increasing the velocity, roughness effects are reduced, and numerical values get close to the experimental values. Also, with the surface temperature passing through the saturation temperature, the heat transfer rate was significantly increased by this mechanism.
