F091002 差分格子ポルツマン法による流体音の直接計算([F09100]環境工学企画,数値空力音響の最前線と課題)
詳細
Direct simulations of sounds by the finite difference Lattice Boltzmann Method are briefly described. Two types of models for compressible fluids are introduced, and some simulation results are shown. A model for two-phase flow, air and water, is also introduced and sound in the air and under water sound are directly simulated.
