Interpolation Methods Used for One-Way Fluid Structure Interaction of Hydrodynamic Coupling

Abstract:

In the design and manufacturing process of the hydrodynamic coupling, the fluid pressure on the impeller is difficult to calculate when analyzing the strength of the impeller. We can use the one-way fluid-structure interaction analysis. When interpolate the pressure on the flow field and structural coordinate values, choosing reasonable interpolation method can reduce the amount of computation, improve accuracy, simplify product design and manufacturing process. This article is based on one-way fluid-structure interaction analysis. We compare the four interpolation method in MATLAB, conclude that the spline interpolation is better than others. It is the most suitable for practical applications, which can simplify the design of the manufacturing process of the hydrodynamic coupling.
