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 compariosn a steel duct with surface roughness is also simulated. The duct considered in this study has a cross-section of 300mm X 300mm and len...
