Abstract
In this project is the gas flow characteristic of a helicopter engine exhaust and to derive an optimized geometry for the exhaust duct with minimum pressure loss using CFD analysis. In this project, the variables to be analyzed are the inlet static pressure, velocity and temperature of the exhaust gas at the exit of the exhaust duct. Cylindrical exhaust ducts of various dimensions are modeled by changing the primary and secondary inlet area and the exhaust geometry is optimized based on the CFD results. For the same optimized area of primary and secondary inlet, divergent exhaust duct is modeled and analyzed for various divergent angles. Parametric studies were carried out for a better comparison between cylindrical and divergent ducts for the better thermal efficiency.
