【 摘 要 】

The article describes the basic modeling methods of hydrodynamic processes in screw centrifugal hydrogen pumps using software ANSYS CFD; the variable fluid density is taken into account. Three methods of modeling fluid flow with variable density were proposed in ANSYS CFD. Regression models of variable density were obtained. Regression models characteristics are of the second and fourth order, the pressure range is from 0.09 to 30 MPa and the temperature range is from 18 to 34 K. Regression models were implemented in the method by reference variable density of liquid hydrogen in the form of functional dependence.
