This work is focused on exploring the flow and heat transfer capabilities for slotted and axisymmetric cavity configurations for synthetic impinging jets; the jet is enclosed between two isothermal parallel plates, impinging into the top hot plate. Numerical simulations using the Arbitrary Lagrangian-Eulerian formulation of the Navier-Stokes equations are performed for Reynolds numbers of 50, 300 and 500 and a jet formation criteria of 3. The pattern of the flow from both configurations differ, which result in different impinging behaviors. The slotted jet is wider than the axisymmetric one, showing an increased turbulent mixing and a lower velocity deficit. On the other hand, the narrower jet of the axisymmetric configuration results in less mixing and more penetration, with a higher velocity deficit. This leads to a higher heat transfer peak in the axisymmetric configuration with a faster decay when moving away from the jet centerline than observed for the slotted configuration.

这项工作的重点是探索合成冲击射流的狭缝和轴对称腔结构的流动和传热能力。射流被封闭在两个等温平行板之间，并撞击顶部加热板。雷诺数分别为50、300和500，射流形成标准为3时，使用Navier-Stokes方程的任意Lagrangian-Eulerian公式进行了数值模拟。两种配置的流动模式不同，从而导致不同的撞击行为。开槽射流比轴对称射流更宽，表明湍流混合增加，速度不足。另一方面，轴对称构造的较窄射流导致较少的混合和更多的穿透，并具有较高的速度赤字。
