Numerical simulation of the atmospheric boundary layer and its application – Flow over terrain

چکیده
Shear layer separated from a bluff bodyshaped structure is very sensitive to the inflow turbulence. Appropriate numerical simulation of the atmospheric boundary layer plays key points in the numerical study of the aerodynamic forces experienced by the structures immersed in the ABL. This paper describes the methods to simulate the inflow turbulence corresponding to different surface roughness. As an example of the application to wind engineering problems, the flow field over hills which received combined effects of inflow turbulence and surface roughness are studied.

Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations.

متن کاملApplication of Single Objective Genetic Algorithm to Optimize Heat Transfer Enhancement from a Flat Plate
The optimal shape of a two dimensional turbulator above an isothermal flat plate is found by using numerical simulation. The turbulent boundary layer over the flat plate was disrupted at various situations by inserting a quadrilateral bar where the boundary layer thickness kept more than three times greater than the insert\'s height. As a result, the overall heat transfer coefficient of the wal...
