| The technology of gas-particle two-phase compulsive circumfluence finishing is another kind of finishing method, which is proposed on the basis of spiral gas flow finishing and liquid-particle two-phase compulsive circumfluence finishing. The process of this method is the gas with a certain pressure was pushed through the circulation occurs device, compulsive circulation is formed by the gas. It stimulates particles to make circulation movement. The particles can collide, scratch and rolling the hole surface of workpiece, so as to achieve the purpose of finishing.The primary content of this paper includes:introduced some methods of hole surface finishing; expounded the theoretical knowledge and applications of spiral flow and two-phase flow; done theoretical analysis of the method of two-phase flow finishing; simulated, analyzed and compared the gas-particle two phase compulsive circumfluence finishing by FLUENT, the general sofeware of CFD, so as to design the shape of spral head. At last, designed the whole experimental device of gas-particle two-phase compulsive circumfluence finishing and using the device to verify the feasibility of this method.Clarifing the primary factors of finishing effect through theoretical analysis. Fixing the numerical simulation parameters by these factors. Comparing these factors, and mainly comparing the finishing effects of different inlet dip angel, the diameter of particle etc. Finaly, fixing the optimal parameters of finishing using gas-particle two-phase flow. Designing experiment device and doing experiment under these conditons. Numerical simulation and experiments results can provide some helpful foundation for later research on this subject.
