Sloshing in fuel tanks is one of the major sources of noise in hybrid and high-end vehicles. During sloshing, the fluid causes impacts on tank walls resulting in their vibration, which further leads to noise, referred to as “hit noise.” Therefore

Sloshing in fuel tanks has become a new source of noise in hybrid and high-end vehicles in the wake of reduced noise from major sources like the engine. It occurs due to the interactions of fluid inside the tank under various driving conditions of th
