Abstract
In modern days, automobiles are the most important means of transportation. With the development of automobiles, noises generated during operation has been recognized as a significant factor of performance to provide drivers with better driving environment along with other passengers. In this study, drone noise(pulsating noise), generated at the rear window when its opened, is predicted to understand the physics of its phenomenon at various velocities. The compressible Navier-stokes equation will be used with $6^{th}$ order compact finite difference scheme to analyze the characteristics.
