Figs. 7, 8, and 9 show that as the pressure velocity ratio increases between downstream and upstreami.e. c0/c,, the optimumenergytransfer across the bifurcation occurs at a higher area ratio.
WebDec 1, 2024 · Flow path curvature is responsible for the development of Dean-type secondary motion while flow division at the bifurcation ridge generates secondary motion opposite to that induced by curvature. An increase of flow area from inlet to outlet results in an increase of asymmetry in cross-sectional velocity distribution.
