排水過程における壁面-多孔体間での気液相界面挙動の観察

It is important to understand the liquid-vapor phase interface shape developed by vapor generation on the porous body for the performance prediction of the loop heat pipe. A visualization experiment device, in which a porous body is immersed in the working liquid and its top surface is in contact with a viewing windows with a pore, was constructed to observe the vapor-liquid interface behavior between the porous body and the wall. Drainage process in which vapor invades into the porous body and grows was observed using different porous body materials, working fluids. The liquid-vapor phase interface shape was evaluated from displacement pattern, saturation, and vapor-liquid interline length.
