Noise due to sloshing within automotive fuel tanks
Tóm tắt
The effect of liquid sloshing upon the acoustics of automotive vehicles is becoming more pronounced with the increasing size of fuel tanks and the recent progress in minimising tyre, engine and aero-acoustical noise generation. This paper deals with experiments and numerical simulations of sloshing in automotive fuel tanks. A correlation between recorded slosh noise and simulated pressure fluctuations within the sloshing liquid is derived. The presented numerical simulations are based on the volume-of-fluid method and are able to track the free-surface-flow within complex fuel tank shapes subjected to arbitrary outer acceleration profiles. Some typical applications of the numerical approach are presented, too.
