INFLUENCE OF TEMPERATURE ON INFILTRATION PROCESS OF LIQUID COPPER IN W SKELETON

The effects of temperature on liquid infiltration of molten copper in W skeleton pores are investigated by numerical simulation. The unsteady state infiltration processes of molten copper in the same W skeleton pores are studied at the temperature of 1373K, 1473K and 1593K, respectively. The mobility of molten copper is affected by the temperature, which then lead to the different transport process. The infiltration velocity of molten copper in W solid is affected by viscosity, surface tension and contact angle of liquid copper, which indicates that higher temperature can accelerate the rate of the seepage. The velocity distribution drops down along the infiltration and displays parabolic trend along the position.
