Witryna1 lut 2024 · Most of the existing work have investigated the pressure distribution, thrust force, and impingement force. Considering that jet impingement is a complicated phenomenon that is affected by various factors, the initial flow conditions, break conditions, and target conditions in each experimental study are carefully reviewed. … WitrynaThe jet behaviour from the nozzle to the porous wall is between free jet and impinging jet on a solid surface depending on the porosity. For low porosity ( φ ≤ 0.41), the jet structure is very similar to jet impinging on a solid surface. For high porosity ( φ ≥ 0.65), the flow type may be described by free jet.
