Abstract:

Flow past bluff bodies is a typical situation that may occur in many engineering applications. Such flow involves complex phenomena like separation, reattachment, vortex shedding and turbulence. The numerical modelling of the flow around bluff bodies using computational fluid dynamics (CFD) techniques is a powerful tool to predict such flow by solving the governing equations. Bluff bodies are obstacles with shapes that significantly disturb the flow around them like circular cylinder, square cylinder or even special shape like parabolic trough solar collector. The flow around bluff bodies is sensitive to the change of Reynolds number and has been the subject of both experimental and numerical studies for decades. The present work describes the CFD methodology applied to solve Navier Stokes equations and simulate the flow in a channel with a heated square cylinder. The same methodology was also used to study the wind effects on a parabolic trough solar collector and the heat transfer in the receiver. The numerical results of the flow behavior and heat transfer characteristics will be presented and discussed.
