Gas-liquid-solid multiphase flow multifunctional loop flow field simulation experiment system and method

The invention discloses a gas-liquid-solid multiphase flow multifunctional loop flow field simulation experiment system and method, and the system comprises a gas source region which is used for providing air as a gas phase; the liquid source area is used for providing tap water added with a foaming agent or a defoaming agent as a liquid phase; the mixed flow area is used for providing gravel as a solid phase, so that the gravel is mixed into air and tap water, and gas-liquid-solid multiple phases are formed; the front experiment observation and inspection area is positioned behind the flow mixing area and is used for carrying out flow state observation and performance detection on the entered gas-liquid-solid multi-phase; the to-be-tested equipment mounting area is positioned behind the front experiment observation and inspection area and is provided with to-be-tested equipment; the rear experiment observation and inspection area is positioned behind the to-be-tested equipment mounting area and is used for c
