Flow over a bump
WebTranscribed Image Text: Water flowing through a wide horizontal channel encounters a bump as shown in the figure. y= 0.8 m Vi = 8 m/s Azz =0.30 m Bump Determine the following: a. Surface level over the bump b. Type of water flow over the bump Maximum height of the bump to produce critical flow с. WebThe objective is to optimize the five parameters in turbulence closures using the PINN leveraging limited data available from costly high-fidelity DNS data. We validated this method on two test cases of flow over bump.
