Impingement velocity curve
Witryna5 mar 2024 · Open the bench valve slowly, and allow water to impinge upon the target until the datum line on the weight pan is level with the gauge. Leave the flow constant. Observe and note the flow behavior during the test. Measure the flow rate, using the volumetric tank. Witryna9 lut 2024 · As the water jet impinges on the heated surface, the flow is assumed to divert symmetrically around the stagnation line and extends to the surface in a parallel manner. The velocity profiles in viscous boundary layer and free-stream (inviscid) region are depicted in stagnation and acceleration regions.
