WebJun 15, 2024 · A series of wall-modeled LES were also performed for flo w over the Gaussian bump, using the same domain and boundary conditions as the DNS in order to isolate the effects of the turbulence ... 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.

WebJun 1, 2024 · A bump is typically used in the inlet system of an aircraft engine to compress the incoming airflow and to reduce boundary layer thickness developed over fuselage. In this work, the turbulent flow over a three-dimensional bump is experimentally studied. The bump model is mounted in a closed return wind tunnel operated at the nominal velocity … tsg charge.ie

WebNov 21, 2024 · At low speeds, the air flows splits when it meets an object and, providing the object is reasonably aerodynamic, flows right around it, closely following its outline. But the faster the air flow and the less aerodynamic the object, the more the air flow breaks away and becomes turbulent. That's what we mean by form drag. WebJan 20, 2024 · The flow of ice over a bump under steady-state conditions has been studied both experimentally and numerically. The experiments were performed with the ice viscometer installed at the Laboratoire de Glaciologie et Géophysique de l'Environnement du C.N.R.S. (LGGE) in Grenoble, France.
