Time Step

It is pointed out that the influence of the time step in the unsteady non-uniform sediment mathematical model must be considered when to calculate the mixed-layer thickness in this article. And then a new method to calculate the mixed-layer thickness is obtained based on the sand wave movement. This method can well reflect the effect of the time step on the mixed-layer thickness, and has a wide field of application in the numerical simulation of natural river sediment transport.

Main Factors

For the precise hole surface, the burr severely affects products’ performance. Considering the specific conditions of the precise hole surface finishing, a new method of two-phase compulsive circulation flows finishing is brought up. Nozzle number, nozzle position, liquid flow, etc. are main factors, which would directly influence finishing effect and efficiency. Affecting rules of main factors are studied by experiments and numerical simulation, which provide basis for thorough research.
