Due to advancement in automobile technology, various types of automobile noises have been reduced significantly and hence sloshing noise has become a major irritant for passengers. Past studies have concluded that the slosh noise is directly connected with the pressure fluctuation dp/dt which in turn can be provided by CFD study of flow dynamics of working fluid in the fuel tank. The present work includes experimental and CFD study of flow dynamics of working fluid in a rectangular tank. Experiments have been performed on indigenously developed Impact test setup. Experiments were conducted with varying fill level, varying sensor location and varying deceleration and the axial acceleration from experiment has been taken as input for CFD analysis. Commercial CFD solver STAR CCM+ was used to perform the CFD simulations. Image validation and dynamic pressure validation has been done to compare the CFD results with experiments
