PROPOSAL OF FLUID FORCE FUNCTION FOR CROWD EVACUATION SIMULATION IN INUNDATED AREA

Abstract

 In the prediction of numerical simulation for the crowd evacuation behavior under inundated underground, accurate evaluation of the hydrodynamic interaction forces between violent flows and evacuees will be demanded. However, this kind of simulation brings high computational load due to the computation of violent flows in the wide underground area. Increasing the feasibility of the inundated crowd evacuation simulation needs increasing computational efficiency. The fluid force function regarding the hydrodynamic force acting on the evacuee based on the numerical results using DEM-MPS coupling model is proposed in the present study and indicating this function will allow to save computational time sufficiently.
