Water jet impingement onto a moving steel strip surface was numerically simulated using a three-dimensional computational model. A continuous supply of cooling water causes residual water to accumulate on the moving strip surface, which reaches a certain water level according to the flow rate. Because this residual water significantly affects the water jet impingement and strip cooling, it is essential to accurately reflect its level in a simulation of strip cooling. In this study, we developed the concept of artificial sidewalls to apply a more realistic residual water level to a cooling simulation. For various water jet flow rates and longitudinal domain sizes, the residual water levels and impinging pressures were compared in cases with and without these artificial sidewalls.
