APPARATUS FOR SINGLE-PHASE PARTICLE SIMULATION OF TRAPPED AIR BUBBLES IN LIQUID FLOW

摘要

PURPOSE: A single phase particle simulation apparatus is provided to simplify a process of air bubble by using an SPH(Smoothed Particle Hydrodynamics) particle simulator without change of a structure. CONSTITUTION: An air bubble generating module(141) determines a generation location of air bubble inside an air pocket and models the air bubble as a lightweight rigid body. An air bubble interaction calculating module(142) calculates interaction force based on collision based boundary force. An air bubble removing module(143) deletes the air bubble.
