Turbulent Flow over Cars

In this paper the flow behaviour over a number of car bodies is studied. For this purpose the unsteady 2-D incompressible Navier-Stokes equations have been applied. After averaging and nondimensionalizing the equations, the system of equations has been transformed from the Cartesian (x-y) coordinates to a body fitted generalized (-) coordinate. As the flow is incompressible, the density in the ...

Energy Transfer Analysis of Turbulent PlaneCouette Flow ?

An energy transfer analysis of turbulent plane Couette ow is performed. It is found that nonlinear interaction between the 0; 1] modes is principally responsible for maintaining the mean streamwise turbulent velocity proole. The 0; 1] modes extract energy from the laminar ow by linear non-modal growth mechanisms and transfer it directly to the mean ow mode. The connection of this work to linear...

Numerical Simulation of Turbulent Subsonic Compressible Flow through Rectangular Microchannel

In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...
