Abstract
In urban areas, where space is limited, micro wind turbines can be installed on rooftops or structures near buildings. Studying the flow around cylinders near a flat wall is important for understanding how the presence of buildings affects the performance of these micro wind turbines and how they can be optimized to operate in urban environments. This study employs the Pseudospectral Fourier method coupled with the Immersed Boundary method in simulations involving flow around a circular-based cylinder near a wall. This work presents simulations that demonstrate the influence of local Reynolds number with the introduction of a wall, as well as the influence of varying the distance between the cylinder and the wall, referred to as "GAP," on the formation of the vortex wake. The results are compared with other works: experimental and numerical.
