Sloshing effect of back pressure fluctuation of oil filling pipe in oil tank inheavy sea

Abstract

During the loading operation of the oil tanker, the oil sloshing is caused by the movement of the carrier liquid and the filling of the liquid cargo. The sloshing force acts on the filling pipe and affects the filling process of the tanker. The main aim of this paper is to back pressure fluctuation of oil filling pipe in oil tank. A more reasonable three-dimensional model was established, and the VOF (volume-of-fluid) model was combined to simulated the change of back pressure. This paper firstly compares the sloshing loads caused by tank loading and movement. The results show that the effect of tank loading on the back pressure of the filling pipe is less than the impact of the tank movement. On this basis, the article further studies the sloshing effect of the tank movement. The test simulated different amplitude of tank to compare and analyze the back pressure variation characteristics of the filling. The results of simulation show that during the tank loading operation, the sloshing pressure load becomes larger as the motion period decreases.
