In this study CFD simulation is done on two types of metallic duct design to investigate the pressure drop of flow through an elbow. The PU/PIR duct is new and fast growing integrated material of aluminum and insulation material compacted together to achieve thinner overall thickness as compared to conventional steel ducting with insulation wrapped around it. As compare with sheet metal duct fittings,...
The PU/PIR duct has texture of 0.5mm height along the duct. This study focus on the frictional loss of flow through a rectangular duct of PU/PIR duct. As a comparison a steel duct with surface roughness is also simulated. The duct considered in this study has a cross-section of 300mm ?? 300mm and length of 1500mm. The two designs are simulated in FLUENT proprietry software. The Hybrid tetrahedral...
