Abstract
An anodic electrophoretic method has been used to create a uniform thin film coating on thin steel plates. The changes in the contact angle of the plates have been carefully measured. Then the samples were tested in a boiling pool to measure the critical heat flux and the boiling heat transfer coefficient. For the numerical simulation of plates with different wettability, after validation, by changing some of the boiling parameters to parameters that depend on the contact angle, the critical heat flux has been calculated for variable contact angles. The experimental results and numerical simulation are close to each other and show a similar trend. These results are also compared with other experimental data and their difference is less than 5%.
