PROBLEM TO BE SOLVED: To make a liquid flow rate close to a desired value when gas and liquid are mixed and the mixture is supplied as a gas-liquid two-phase flow to a measuring object. SOLUTION: This gas-liquid two-phase flow supply device 20 includes an outer pipe 22 whose one end is attached to one side surface of a porous body 12 as the measuring object, and an inner pipe 24 that is arranged inside the outer pipe 22 while the axis is aligned and whose one end is separated from one side surface of the porous body 12 at an optional interval. Liquid is supplied from the other end of the inner tube 24, gas is supplied from the other end of an annular pipe section 26 between the outer pipe 22 and the inner pipe 24, the gas and liquid are mixed in a space 28 between one side surface of the porous body 12 and an opening of the inner pipe 24, and the mixture is supplied as the gas-liquid two-phase flow to the porous body 12. Using the gas-liquid two-phase flow supply device 20, a gas-liquid two-phase flow evaluation system for measuring the pressure loss of the porous body 12 is constituted. COPYRIGHT: (C)2009,JPO&INPIT
