Abstract
In order to investigate the stability limit and movement of motor vehicles in tsunami flooding,and the drift andcollision behavior to the tsunami evacuation tower, both physical and numerical model experiments have been carried out. For the numerical study, Ladd's Lattice Boltzmann Method (LBM) model for particle suspension, which has been extended with free surface and SGS turbulence model, is further modified to satisfy the simulations of motor vehicles with irregular shape. The interactions between fluid and vehicle body, and vehicle and vehicle are numerically simulated by the exchange of momentum, due to the application of link-bounce-back scheme for the movable solid particles in the fluid.The present numerical model is verified through the physical experiments using up to 80 car models.
