“…This is called liquid sloshing, which is a source of noise generation in an automobile. [3][4][5] Due to sloshing, complex surface waves are generated and dynamic forces are exerted on the tank walls. This results in noise generation that is typically referred as sloshing noise.…”

In order to reduce the influence of fuel sloshing on the interior noise of a passenger car, the fuel tank sloshing noise was first evaluated with a subjective evaluation method to determine the driving cycle of the car and the fuel filling percentage of the fuel tank in which the fuel tank sloshing noise is serious, and then two anti-wave boards with different structural characteristics were designed to reduce the fuel sloshing. On this basis, fuel sloshing in the fuel tank equipped with the newly designed and original anti-wave boards was simulated numerically; then, the anti-wave board with the best effect of inhibiting fuel from sloshing was selected based on the numerical results; finally, the anti-sloshing effect of the selected board was evaluated through the car road test. The test results show that the vibration acceleration magnitude at each monitoring point of the tank with the selected anti-wave board is significantly reduced compared with the original fuel tank, which indicates that the selected anti-wave board inhibits fuel from sloshing greatly.

“…He used two-phase Computational Fluid Dynamics (CFD) to track liquid interface within realistic tank geometries to determine these pressure fluctuations. Kamei et al [3] also determined a sloshing noise correlation that relates factors pertaining to the fuel tank, body parts and tank mounting structure. The tank mounting structure which is related to both the fuel tank and the body parts has the largest contribution to sloshing noise.…”

“…is the volume of the computational cell, S is the surface area of the computational cell normal to the velocity vector v.The VOF model assumes that velocity, pressure, and temperature fields are shared by all immiscible fluid phases present in a control volume The equations describing mass, and momentum are solved in the same way as it is solved for single phase flow but for an equivalent fluid whose physical properties are calculated as a function of the volume fraction of the constituent phases in the computational cell. The transport properties like density and viscosity are given as,3 where, ρ i and µ i is the density and viscosity of the i th phase. The sum of volume of fractions of all the phases in any given computational cell is unity.While using the VOF model, only one single momentum equation is solved.…”

With significant decrease in the background noise in present day automobiles, liquid slosh noise from an automotive fuel tank is considered as a major irritant during acceleration and deceleration. All major international OEMs and their suppliers try to reduce sloshing noise by various design modifications in the fuel tank. However, most major activities reported in open literature are primarily based on performing various CAE and experimental studies in isolation. However, noise generation and its propagation is a multiphysics phenomenon, where fluid mechanics due to liquid sloshing affects structural behaviour of the fuel tank and its mountings which in turn affects noise generation and propagation. In the present study a multiphysics approach to noise generation has been used to predict liquid sloshing noise from a rectangular tank. Computational Fluid dynamics (CFD), Finite Element Analysis (FEA) and Boundary Element Method (BEM) simulation studies have been performed in a semi-coupled manner to predict noise. VOF based multiphase model along with k-ε turbulence model was used to perform the CFD studies. Sloshing Noise generated due to fluid interaction with structural walls is simulated using Vibro-acoustic model. An integrated model is developed to predict dynamic forces and vibration displacement on tank walls due to dynamic pressure loading on tank walls. Noise radiated from tank walls is modelled by Harmonic Boundary Element Method. Experimental and numerical studies have been performed to understand the mechanics of sloshing noise generation. Images from high speed video camera and noise measurement data have been used to compare with numerical models.
