APPARATUS OF TESTING LDI(LIQUID DROPLET IMPINGEMENT) EROSION INDUCED BY HIGH SPEED 2 PHASE FLOW

摘要

PURPOSE: A droplet collision erosion inspecting device cause by collision of high-speed two phase fluid is provided to simulate various erosion phenomenon caused by moisture while controlling a speed of fluid, a water content of the fluid, a distance between a material specimen and a spray nozzle. CONSTITUTION: A droplet collision erosion inspecting device cause by collision of high-speed two phase fluid comprises an air compressor(10), an air storage tank(20), a compressed air feeding line(30), a spray nozzle(50), a water feeding line(60), a flow rate control valve(70), and a case(80). The air compressor generates compressed air. The air storage tank stores the compressed air generated by the air compressor. The compressed air feeding line transferring the compressed air stored in the air storage tank. The spray nozzle is connected the compressed air feeding line. The water feeding line is connected to the spray nozzle. The flow rate control valve is arranged in the water feeding line.
