EXPERIMENTAL STUDIES OF UNSTEADY FLOWS AROUND RECTANGULAR PRISMS

Parametric study of flow around rectangular prisms using LES

A parametric study concerning the flow around rectangular prisms of different aspect ratios (1 : 1, 1 : 1.5, 1 : 2, 1 : 3, 1 : 4) is conducted numerically at a Reynolds number of 105. The Navier—Stokes equations in the large eddy simulation (LES) framework are solved using a finite volume method. The Smagorinsky closure model is used for representing the subgrid scale viscosity. The simulated r...

Computational Study of Unsteady Flows around Dragonfly and Smooth Airfoils at Low Reynolds Numbers

A computational study was conducted to investigate the unsteady quasi-two-dimensional flow around a streamlined NASA low-speed GA(W)-1 airfoil and a corrugated dragonfly airfoil at the Reynolds numbers of 68,000 and 55,000. Both 2D and 3D simulations were carried out by solving the unsteady Navier-Stokes equations to predict the behavior of the unsteady flow structures around the airfoils at di...
