摘要：

A confined laminar two-dimensional submerged jet impinging on a flat surface has been studied numerically. The transport equations were solved using hybrid differencing schemes (upstream-weighted and upstream differencing schemes). The jet nozzle exit velocity profile was assumed to be fully developed. Effects of the length of the confinement plate, the jet Reynolds number and the jet-to-plate spacing on the flow characteristics were investigated. For long lengths of the confinement plate, the flow field is dominated by a recirculating vortex near the confinement plate together with a smaller vortex on the impingement plate. For short lengths of confinement plates, the recirculating vortices disappear and an inflow to the jet along the confinement plate becomes well established.
