Air flow in a bent rectangular duct with Ansys Fluent

Rectangular channels are widely used in air distribution systems to supply or return air. Bends are fittings used to change flow stream direction. This case study deals with air flow in rectangular duct with three elbows. The aim was to evaluate the hydraulic resistance coefficient and discuss physical phenomena such as flow separation and secondary flow appearance. The total loss coefficient covers both friction and minor (local) losses between the first bend inlet and last bend outlet. Results from numerical simulations are compared with available theoretical data.
