Flow over a bump
WebThe highest bumps create a small separation bubble, whereas flow over the lowest bump does not separate. The log law is absent over the entire bump, evidencing strong disequilibrium. This dataset was created for data-driven modelling. An optimization method is used to extract fields of variables that are used in turbulence closure models. WebIn accordance with the nearest-depth rule, the flow depth over the bump is equal to approximately 1.10 m. (b) The maximum height of the bump to avoid choking causes critical conditions to occur over the bump. Under this circumstance, the energy equation requires that.
