Impact threshold velocity
Witryna25 lip 2024 · Then, the wind velocity u 1 (fluid threshold velocity) at 0.6 m (6 H) was recorded. The threshold velocity \(u_{t}\) values of 0.28 and 0.15 mm silica sands were 5.2 and 4.5 m/s, respectively. A linear relationship between the threshold velocity and the friction velocity in the flow field exists. WitrynaThreshold velocity of water impact is derived for wedges with various deadrise angles, of which model test was carried out for the validation. A new concept of equi-added-mass lines is introduced to take account of the hull form to compute substantial relative velocity between hull and wave surface. ...
