- Abstract
In this paper, the mixed abrasive jet mixing chamber was used as the research object, and the mixing efficiency was improved by introducing the flow around the cylinder in the mixing chamber to enhance the chaos of the flow and promote the turbulence fusion. The three parameters of cylindrical azimuth, feature size and axial position are designed and optimized by theoretical analysis, and the optimal scheme is given and the concrete implementation method is pointed out. In order to further verify the feasibility and practical effect of the scheme, this paper uses the computational fluid simulation software to simulate the mixing process in the two mixing chambers with or without cylindrical flow, and obtain the distribution cloud of the abrasive at the time of mixing. The comparison results show that the mixing effect of the mixing chamber is larger than that of the ordinary mixing chamber, which shows that the scheme is feasible and has some guiding effect on improving the mixing effect.
