Noise Reduction Using Chevron Nozzles in Jet Engines, ANSYS Fluent In this project, noise generation from two types of nozzles (a regular one and a chevron nozzle) is simulated and analyzed using ANSYS Fluent software. Aeroacoustics is a branch of fluid dynamics dealing with the theory of noise generation in flows. Aeroacoustics phenomena are responsible for noise generation from aircraft engines, jet flows, drone propellers, etc. Chevron nozzles are a type of nozzle design used on jet engines, particularly on the engine’s exhaust system. They are characterized by their sawtooth pattern on the trailing edges of the nozzle. This pattern helps to mix the exhaust gases more efficiently with the ambient air. Chevron nozzles break up the high-speed exhaust jets into smaller, more manageable segments. This helps in reducing the noise generated due to the shearing effect when the high-speed jet exhaust mixes with the slower-moving ambient air. The improved mixing facilitated by chevron nozzles leads to a quieter operation, which is particularly beneficial for aircraft operating near urban areas. The geometry is designed in SpaceClaim and is meshed using ANSYS Meshing. The area around the nozzle is meshed unstructurally, while the rest of the domain is meshed structurally. The element number equals 989,310 for the chevron nozzle and 1,317,762 for the regular nozzle. https://lnkd.in/djTVYHiu
