Abstract


The sloshing of liquid is occurred in a large variety of applications like reservoir containing liquid fuel, Liquefied Natural Gas (LNG), water and etc. In this paper, the critical frequency was found by comparing exciting frequency. The effects of density enhancement on decreasing the amplitude of produced waves and also the pressure imposed on the tank was investigated for various amounts of density. The critical frequency was found by comparing the exciting frequencies of the tank. The gauge pressure imposed on the roof and wall also was investigated in different points. In this paper, the critical areas on where the maximum pressure was applied, is shown. Upper phase density enhancement up to a special point was effective in reduction of sloshing and pressure wave altitude but as this enhancement increases, hydrostatic pressure goes up. The optimum density of the gas phase is p 200 kg3 m m = that reduces the interface sloshing and does not increase the pressure any more.
