N2 - This article addresses the issue of supersonic steam jet interaction with the wall. Steam has been impinged in a wall using a nozzle at different pressure values ranging from 1.5–3.0 bars. The whole fluid domain is comprised of regions, that are the body of the jet and the fluid region near the wall. Within this region, the transformation of primary vortices into secondary vortices occurs and these vortices expel outward in the radial direction after impingement. Measurements have shown the spreading of the normalized density of the vortical structures along the axial length within the region near the wall. However, the probability density function analysis has indicated that the vortical structures become denser within the impingement region. In addition to the steam interaction with wall, along the radial direction, weak traces of their existence in the jet region may be attributed to the vorticity diffusion within the jet region.
