• A porous-plug is one of important components for onboard cooling systems which separates the vapor from the liquid helium (He II). Flow characteristics through porous-plugs and physical situations of He II flow inside pluge are experimentally investigated by examining the temperature distributions inside plugs. It is clarified that He II flows ideally, i. e. London's relation is held, in flows through the most part of a plug and turns into vapor phase near the downstream end of it. The flow of the normal fluid component remains laminar in plugs in any experimental conditions. The liquid-vapor phase boundary is formed just at the downstream end and goes down toward the upstream side as the mass flow rate increases. The thermodynamic states of He II are also revealed from these flow characteristics.
