The study of interfered flows for the development of the thickness of the boundary layer using spires

A wind tunnel is a research tool that is used for studying the effects of air moving over or around the solid objects when air is blown through the inlet of the wind tunnel. The boundary layer developed in the wind tunnel has been of great research interest, as this helps to study and simulate the atmospheric boundary layer. The inlet flow is obstructed to enhance the thickness of the boundary layer. The obstructions used generally are the spires, baffles and wedges. Such an obstructed flow is called the interfered flow.;The main objective of the present research is to study the effect of interfered flows on the boundary layer thickness. For this purpose GAMBIT is used as the modeling and meshing software and FLUENT is used as the analysis software. The boundary layer profiles are obtained in the FLUENT for different heights, shapes and number of the spires. Also the distance between the spires is varied while using the above parameters in combinations. A total of 36 case files are generated for the purpose.
