Resumo
The numerical results of studying the impact of an axisymmetric liquid jet upon a flat rigid wall covered by a layer of similar liquid are presented. Primary attention is paid to the effect the layer thickness on the wall has on loading in the range of impact velocities 150–350 m/s. The loading character is studied, and the estimations of wall pressure are obtained in the case of a small layer thickness, which are topical for the applications associated with the droplet and cavitation erosion. It is shown that under the conditions considered the known results of two-dimensional modeling overestimate the maximum of the average pressure on the wall by 1.8 times.
