Optimal blowing parameter research of compressible flow controlling dust from cold rolled strips

Puts forward a spurt compressed air ventilation system to control bursting and movable dust source from the strip steel. Numerically simulates the fluid field of the blowing compressed air dust source control device, and the result shows that the optimal nozzle installation degree is about 0 to 5°. The static experiment results show the correctness of the numerical simulation results. The pilot-scale field test shows that the blowing flow with appropriate parameters can effectively control dust pollution.
