Abstract: Convergent-Divergent nozzle, CD nozzle is a tube with an asymmetric hourglass shape with converged diameter at the center, assembling the nozzle precisely and perfectly balanced. Convergent-Divergent nozzle rushes pressurized hot gas flowing at supersonic speed at thrust direction by converting heat energy into kinetic energy. With this advantage the Convergent-Divergent nozzle is used in many types of Steam Turbines, Rocket Engine nozzles and Supersonic Jet Engines. The present paper describes the design of CD nozzle in solid works and study of heat transfer coefficient in CD nozzle using D.R. Bartz equation.
Keywords: CD nozzle, D.R. Bratz equation, heat transfer coefficient (HTC), Mach number.
Scope of the Article: Low-power design.
