Abstract:

In general, curved 90° elbow bends of air-conditioning, ventilation duct systems and the mill-duct conveying systems shows less energy losses and higher production cost compared to right-angled sharp 90° elbow bends. Formation of a separation zone in sharp elbow bends causes energy loss, which appears just after the corner, questionable and difficult to make numerical prediction of the flow.  By using the computational fluid dynamic software’s Gambit & Fluent, geometry of the duct and flow pattern inside the duct can be modeled and visualized. Due to high pressure generation in every inlet port of the duct at full load condition, the flow should be highly streamlined but it is not created because of the poor geometry of the duct.
