Induced wheel cavitation test system and method with temperature control and visualization functions

The invention relates to a cavitation visualization test system and method, in particular to an induction wheel cavitation test system and method which are used for a pumping pressure type low-temperature liquid rocket engine and have temperature control and visualization functions. The method is used for overcoming the defects that a medium heat effect is not considered in an existing induced wheel cavitation test, and visual observation of cavitation flow in an induced wheel cannot be achieved. The induced wheel cavitation test system with temperature control and visualization functions comprises a water storage mechanism, a test mechanism, a high-speed camera shooting mechanism and a temperature control mechanism, a test shell made of a transparent material is adopted in the test mechanism and is matched with a high-speed camera mechanism to realize high-definition shooting of cavitation flow in the test piece; closed-loop control formed among a heating device, a controller and a temperature sensor in the
