Heat transfer is an important and influential factor in the design of internal combustion engines. Accurate prediction of heat transfer has a great impact on the design of cooling system of internal combustion engines. And the simulation of internal combustion engines for the purpose of their thermal analysis is done using computational fluid dynamics along with boiling simulation. In this article, investigating the subcooled boiling flow of pure water in a small channel and its dependence on different parameters such as working pressure, heat flux, mass flux. And the subcooling temperature of the inlet fluid is of interest. Numerical simulations were performed using axisymmetric models and the effect of different grid sizes on the accuracy of the results was investigated. The bubble separation diameter was also studied and its relationship with pressure, heat flux, mass flux and temperature under the inlet coolant was analyzed. Finally, a database of generated simulation results and predictive models for bubble dynamics using machine learning algorithms were presented.
