Abstract
Basic methods of modeling hydrodynamic processes in hydrogen screw-centrifugal pumps using the ANSYS CFD software are described in the paper, including those that take into account variable density of the fluid. Compressibility of liquid hydrogen caused by temperature and pressure changes, despite the alowances of average density, requires taking into account variable density for improved accuracy of modeling the workflow of hydrogen pumps. A technique of CFD-modeling of hydrogen pumps using special software tools to build the geometry and grid models of interblade channels is presented. Three methods for modeling variable-density fluid flows in ANSYS CFD are proposed. Regression models of the second and fourth orders have been obtained in the pressure range from 0.09 to 30 MPa and in the temperature range from 18 to 34 K to implement the method of setting variable density of liquid hydrogen in the form of functional relation.
