In a divergent duct
Webas air flows through a divergent duct and is compressed. A temperature rise is also noticed since compression is a heating process. The convergent duct operates exactly in reverse … Web•In the divergent portion of the nozzle the flow expands supersonically, and again the Mach number (supersonic now) is governed by the local value of / ∗. •The resulting variations of …

WebFor two cases of convergent-divergent duct system configuration simulation, power coefficient is obtained and it is compared with analytical solution as shown in Figs. 13 … WebThe usual configuration for a converging diverging (CD) nozzle is shown in the figure. Gas flows through the nozzle from a region of high pressure (usually referred to as the chamber) to one of low pressure (referred to as the ambient or tank). The chamber is usually big enough so that any flow velocities here are negligible.
