低圧鋳造における湯流れの水モデル実験と数値解析

抄録

  Velocity field in a low pressure die casting was measured and compared with computer simulation. In the experiment, water was pushed up by gas pressure into transparent molds. The velocity in the water was measured by using nylon particles and laser beam. In the simulation, measured pressure was used for boundry condition. Shape of the water front and velocity in the water were rather well simulated until turbulent occurred.
