The flow in the impingement region of an axisymmetric jet impinging normally on a flat plate has been studied numerical analytically and experimentally. As it is conceivable that the laminar flow and turbulent flow coexist in the impingement region, the viscous flow model and turbulent flow model that are able to calculate a high Reynolds number flow were used in the numerical analysis. Even either numerical analysis, the impingement region obtained experimentally was adopted as computation domain and the velocity distribution of a free jet was supposed at the inflow boundary. As a result, it was understood that both computation results reproduced the general flow pattern of the impinging jet and agreed well with the pressure and velocity distributions obtained by measurement. However, it became clear that as for the velocity distribution in the boundary layer one of the analyses used the turbulence model agreed well with the measurement results.
