Abstract

Due to vehicle acceleration or deceleration, fuel inside and automotive fuel is subjected to inertial acceleration or deceleration, which causes to slosh thereby generating sloshing noise. In the premium segment of cars this noise is considered to be an irritant to passenger because of low background noise. As part As part of an ongoing research project at IIT Hyderabad, both experimental and CFD studies are be performed to understand and predict this sloshing noise. As part of my MTech thesis, two-phase, multi-dimensional and time-accurate CFD simulations were performed to simulate liquid sloshing for a rectangular tank. Commercial CFD solver STAR CCM+ was used to perform the CFD simulations. VOF multiphase model was used to track the evolution of the liquid surface for different acceleration values. Images from high speed video camera was used to validate the current CFD simulations. Parametric studies on the effect of acceleration amplitude, frequency and fill level on liquid sloshing behavior was studied.
