Implementing Biomimicric Owl Wing Pattern for Noise Reduction in Turbine Blade

The objective of this project is to reduce the noise level which is coming out from the turbine blade in jet engine by implementing owl wing pattern. During the take-off and landing, the noises coming out from the jet engines cause noise pollution. It also provides the irritating to nearby houses, colleges, and schools. During testing of jet engines, the noises from the jet engines cause irritation to technical staff, workers, and it may cause damages to their ears. Model the turbine blade by implementing the owl wing pattern and testing the noise level by modal, harmonic response, and harmonic acoustics analysis. This analysis gives the results in the form of sound pressure level (SPL) in dB. This experiment is modelled by the Catia V5R17. This analysis is done by Ansys 18.2. The comparison was made between the normal turbine blade and owl wing pattern turbine blade and the results are obtained from harmonic acoustics analysis. The SPL values are obtained from the normal turbine blade 143 dB which is greater than the owl wing pattern turbine blade 138 dB. Based on the SPL analysis, the serrated owl wing turbine blade is the best suitable design to reduce the noise which is coming out from the turbine blade.
