  1. Trade / Communities Ship Hydrodynamics: Sloshing Research purpose/impact Natural gas has become an increasingly important source of primary energy for developed countries such as the UK and sea borne liquefied natural gas (LNG) is a vital component in the infrastructure for the national energy security. Because of increased demand and economies of scale, larger LNG ships and facilities are designed and built. Violent liquid motion known as sloshing in the LNG tanks due to external excitations can have significant effects on the safe operations of LNG carriers and storage tanks so it is critical to have deep understanding of sloshing and efficient modelling techniques. • Research description • Development of methodology and techniques for sloshing simulations in partially filled containers and prediction of sloshing impact with fluid structure interaction effect: • (A) Application of a mixed finite element method for sloshing analysis with fluid-structure interactions: A variety of tank sloshing problems have been studied. • (B) Coupling between ship motion and sloshing: A method for coupled ship motion with partially filled tanks is formulated based on potential flow theory. Added mass and motion RAOs are calculated. • (C) A unsteady RANS model for nonlinear sloshing simulation: Modelling techniques are developed and validated utilising experimental data for high fidelity nonlinear sloshing simulations using URANS CFD. • (D) Solution of low speed two-fluid flows occurring in liquid sloshing in an enclosed container: Free surface waves due to sloshing are captured and tank wall pressure time histories are obtained. • (E) A rapid sloshing prediction model based on analytical approach: A faster than real time method is developed using nonlinear pendulum model to predict the sloshing occurrence and severity for LNG carriers in seaway under different conditions.
