A method for increasing the critical heat flux at boiling by applying porous structures of various regular geometries to a smooth surface is considered. The analysis of experimental data and calculation of the critical heat flux based on the model of V.V. Yagov, which considers the additional inflow of liquid into the evaporation zone due to the action of capillary forces in a porous space. Comparison of experimental and calculated data allows us to conclude that this model is not suitable for all microstructured surfaces.
