Optimization of the Flow Part of an Axial Pump Using the Response Surface

To design high-efficiency vane pump flow part it is necessary to use various optimization algorithms, based on which the geometrical parameters of designed flow part are changed in order to provide the required value of some integral design parameter. The article considers the numerical method for finding an extremum based on one of the algorithms included in the DesignXplorer optimization tool, which is an integral module of the Ansys Workbench software package. Response Surface Optimization (RSO) is a kind of mathematical model (metamodel) describing analytical dependence of output parameters on input parameters. The function is based on the approximation of the numerical experiment data (Design of Experiments). The use of this method allows obtaining more efficient flow path of the catalog axial pump OP-5 without performing lengthy experimental research of the effect of the geometric parameters of the flow path on the pump characteristics.
