Numerical Research on LNG Tank Leakage Effect on Environment for LNG Bus

Study and analysis the fuel leakage security of current LNG alternative fuel bus. Do the simulation on surrounding concentration and temperature of LNG bus fuel tank leakage by Computational Fluid Dynamics (CFD). By analyzing the influence of three different bus velocities, 0km/h, 30km/h and 80km/h, we have the conclusion from the simulation that when the bus gets faster, the influence of surrounding becomes smaller.
