Cfd simulation of leaked gas dispersion for a lng powered ship

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this work, computational fluid dynamics (CFD) simulations have been conducted on leaked LNG vapor diffusion in which the gas is discharged from the vent post of a LNG powered RORO ship. A numerical model is proposed based on an open source Computational Fluid Dynamics (CFD) tool called OpenFOAM® for numerical simulation of the turbulent gas diffusion. The numerical method is first validated against a benchmark case and an experimental case. Two turbulence models, k-ε and LES, are applied and the numerical results are compared and discussed. By using the proposed numerical model, a series of LES simulations have been conducted on the LNG vapor diffusion of the RORO ship under several wind speeds and air temperatures.
