Experimental investigation to particle velocity and concentration of gas-solid jetting flux in sand and dust environment

Digital particle imaging technology (DPIV) is adopted to experimentally investigate sand particle velocity vectors and concentration, which are instantaneously measured in sand and dust environment. The experimental results reflect the rules of particle velocity and spatial distribution in gas-solid jetting flux. The disciplinary cognition motivates to develop sand and dust equipment homemade and to confirm the way of supplying sand and dust and the parameter of test segment.
