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 … This nozzle configuration is called a convergent-divergent, or CD, nozzle. In a CD nozzle, the hot exhaust leaves the combustion chamber and converges down to the minimum area, or throat, of the nozzle. The throat size is chosen to choke the flow and set the mass flow rate through the system. See more Ramjets, scramjets, and rockets all use nozzles to accelerate hot exhaust to produce thrust as described by Newton's third law of motion. The amount of thrust produced by the … See more where mdot is the mass flow rate, r is the gas density, V is the gas velocity, and A is the cross-sectional flow area. If we differentiate this … See more Combining this equation for the change in pressure with the momentum equation we obtain: using the definition of the Mach number M = V / a.
