Numerical Modeling of Normal Turbulent Plane Jet Impingement on Solid Wall
Publication: Journal of Engineering Mechanics
Volume 110, Issue 10
Abstract
Jet impingement on a solid wall is a common problem for engineers. Near solid boundaries, flow situations depend highly on the impingement geometries. Therefore, it is almost impossible for engineers to labor through experiments on a case‐by‐case basis. In this study, the major effort was concentrated on a turbulence numerical model of a well‐developed normal plane jet impingement on a solid wall. As a result, different jet impingement geometries can be expressed as different boundary conditions. The two‐equation, turbulence model combined with the continuity equation and the transport equation of vorticity is adopted to solve this problem. An iterative finite difference technique is utilized in the computations. It has been found that the best prediction can be achieved when the wall turbulence Reynolds numbers fall within the range 100–150. The peak levels of turbulent kinetic energy occur not only in the zone of impingement but also in the intermingling zone between the edges of the free jet and the wall jet.
