摘要
The sloshing in a tank with a specific geometric shape containing fluid was modeled numerically to reduce its effects by applying a porous medium to the tank wall.The thickness and position of the porous layer and the geometric shape of the tank were investigated as the main parameters to select an optimal approach to reduce the effects of sloshing.Different fluid tank filling percentages(H_(w)/H_(tot)) were evaluated.Results indicate that performance at H_(w)/H_(tot)=0.33 and two tank modes with and without a porous environment layer have the greatest impact on reducing sloshing.A thickness of 30 cm and placement on the side walls are determined to be the ideal thickness and location of the porous layer.A porous layer with a thickness(t)relative to the tank length at the middle(L_(m)),t L_(m)=0.1 applied to the side walls of the tank effectively reduces the pressure by 65%.This study provided suggestions for the aspect ratio of a chamfered tank designed against sloshing.
