Geometric Parameters

The resistance of an aqueous solution of K2SO4 in an electrolytic cell has been calculated theoretically as a function of geometric parameters of the cell. The calculated values have been verified with a new experimental method using an alternating current of 2000 cycles.

Factors Influencing

Cutting temperature is one of the most important parameters in the cutting process, which has an important influence on the machining accuracy of workpiece, the power consumed by the machining and the degree of tool wear. There are many factors influencing the cutting temperature, such as the properties of workpiece materials, geometric parameters of the tool, the use of cutting fluid and so on. In this paper, we used orthogonal experimental method, with titanium alloy TC18 as the carrier and AdvantEdge as the simulation platform, established the cutting simulation model. With the cutting temperature as the optimization goal, the geometric parameters of the cemented carbide reamer are optimized.

To improve the performance of the centrifugal pump with a vaned diffuser, the influence of impeller geometric parameters on external characteristics of the pump was investigated by Orthogonal Experimental Method (OEM) based on CFD. Blade outlet width b2, blade wrap angle φ, blade outlet angle β2, and blade number Z were selected as the main impeller geometric parameters and the orthogonal experiment of L9 (33*21), which contained 3 levels of the 3 factors and 2 levels of one factor, was done in this study. Three-dimensional steady simulations were conducted by solving the RANS equations in the design procedure with SST k-ω turbulence model, and about 5.3 million structured grids for the whole calculation domains were used. The experimental results were justified by the variance analysis method. The inner flow of the pump was also analyzed in order to obtain the flow behaviors that can affect the pump performance. The results showed that the blade outlet angle β2 had the greatest influence on the efficiency and power. The high efficiency area of the optimal impeller is wider. The final optimized impeller accomplished better pump performance, which meet the design requirements. The velocity distribution in the optimized impeller is more regular and the area of the high turbulence kinetic energy is smaller in the optimal impeller.
