Diverging duct
WebQuestion. A fluid of density p and viscosity u flows through a section of horizontal converging-diverging duct. The duct cross-sectional areas Ala, Alm and Aantlet are known at the inlet, throat (minimum area), and outlet, respectively. Average pressure Poutlet is measured at the outlet, and average veloc- ity Vines is measured at the inlet. WebMay 3, 2024 Ā· Relationship of pressure, temperature, and velocity in a convergent-divergent duct. A duct that has a decreasing cross section in the direction of fluid flow is convergent, until a minimum area is reached. Thereafter, the cross section increases, or becomes divergent. Why does flow separation occurs in divergent section of the flow channel?
