An analytical study was conducted of the contact angle of an evaporating liquid film on a heated wall, which is the most important factor in determining the critical heat flux to cause film breakup. Steady profiles of a rivulet flowing down a vertical heated wall were calculated numerically considering surface roughness. As the liquid film was assumed to the adsorbed o the non-evaporation region, the maximum inclined angle of the liquid film was taken to be the apparent contact angle. The relations among the apprarent contact angle, the inclined angle of the surface roughness and the temperature difference between the wall and the vapor were calculated. When the temperature difference was 5°C, the apparent contact angle of a R113 rivulet was 23°and it was located where the film thickness was 3μm. The apparent contact angle increased in proportion to the temperature difference. The analytical results agreed well with the previous experimental data.
