GAS-LIQUID TWO-PHASE FLUID STATE CONTROL DEVICE AND GAS-LIQUID TWO-PHASE FLUID STATE CONTROL METHOD

摘要

[Problem] To provide a fluid state control device and fluid state control method that are able to easily cause a gas-liquid two-phase fluid to be in a desired fluid state. [Solution] The fluid state control device (100), which causes a gas-liquid two-phase fluid flowing through a supply tube to be in a predetermined fluid state, is provided with: an information acquisition unit (110) that acquires pressure information pertaining to the pressure of the fluid, mass velocity information pertaining to the mass velocity of the fluid, and dryness information pertaining to the dryness of the fluid; and a control unit (120) that, on the basis of the pressure information, the mass velocity information, and the dryness information, controls a pressure regulator valve (31) that can alter the pressure of the fluid, a pump (11) and throttling valve (12) that can alter the mass velocity of the liquid, and a heater (32) that can alter the latent heat of the liquid.
