摘要：The project mainly focuses on the reduction of jet noise emission in the exhaust nozzle of turbofanengines. Numerical analyses have been carried out on various configurations of chevron nozzle to assess theimportance of chevron parameters. The sound pressure level can be calculated from that we determined the noise levelat nozzle exit section. After assessing the chevron parameters we are going to modify the chevrons in order to getmaximum noise reduction along with very negligible thrust loss. ANSYS-Fluent is a commercial Computational FluidDynamics code which will be used for performing the simulation with five different nozzle models-plain and chevronnozzle. The simulation results are evaluated in order to be able to discover the design of chevron nozzle regarding theacoustic power level emitted.
