Numerical Calculation of Acoustic Sources for the Landing Gear of Aeroplane during Take-off and Landing

In this paper we present Orthogonal Sub-grid scale stabilized method with static subscales applied on turbulent flow around landing gear of aircraft during take-off and landing. Numerical results of proposed method are compared with famous LES Smagorinsky method for turbulent flow and it is shown how obtained results affect allocation of acoustic sources and then propagation of acoustic waves in computational domain.
