Ramakanth and Suryaprakash [6] yes,The flow direction is the only homogenous direction which I use periodic boundary condition. Estimation of pressure losses in ducts is vital for the selection of duct size. For any questions and support, join the ANSYS [] Flow in a S-Duct. Please SHARE, SUBSCRIBE and LIKE. The S-duct geometry produces streamline curvature and an adverse pressure gradient resulting in these flow characteristics. When you add a source term, Ansys Fluent will call your function as it performs a global loop on cells. The flow remained attached with the enlarged duct even at L/D = 2; this length seems to be the minimum length needed for the flow to remain attached.
