WebEngineering Mechanical Engineering supersonic nozzle is also a convergent–divergent duct, which is fed by a large reservoir at the inlet to the nozzle. In the reservoir of the nozzle, the pressure and temperature are 10 atm and 300 K, respectively. At … 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 of the divergent duct. Figure 2-3 shows the principle of convergent ducts, where energy is neither being added or taken
WebFeb 22, 2024 · What is a convergent duct? 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. Web2. Divergent diffuser . 3. Convergent-divergent diffuser. The given duct will work as a diffuser or a nozzle depending upon the fluid velocity at the inlet of a duct. Some Applications: 1. Diffusers are used in centrifugal compressor. 2. Diffusers are used in ram-jet engines to increase the pressure of incoming fresh-air.
