Abstract
The atmospheric boundary layer (ABL) flow occurs due the interaction between earth surface and atmosphere and it is usually under thermally stratification. However, the atmospheric wind tunnels need appropriate devices, such as spires and cubical roughness elements, at the entrance of the test section to create atmospheric characteristics. These structures simulate the atmospheric boundary layer far from tunnel inlet. Another ABL feature is the temperature difference for height variation. Hence, the atmospheric fluid stratification will be done with bottom surface heating. In order to study different thermal heating configurations and the boundary layer profile effects under different spires set configuration, a mathematical model will be done and simulated using OpenFoam software. This computational tool is a free open source Computational Fluid Dynamics (CFD) software widely used among researchers across the world. For this problem, the momentum equation and energy equation are coupled and they need to be solved together using the software. The final result will be the analysis of the velocity profile and temperature distribution within the wind tunnel flow.
