Implementation of Regularized Equations for the Disk Pump Simulation Problem in OpenFOAM

Abstract

Creating an effective pump that is able to maintain blood circulation in a heart with appropriate medical indications is undoubtedly a crucial task. First versions of such devices are currently being created and tested on the basis of IFPM SB RAS, Novosibirsk. This work is devoted to a pump numerical simulations in order to optimize parameters. Equations of viscous incompressible fluid flow are used for this purpose. Implemented numerical algorithm is based on the regularization of the initial equations, which applies a finite volume method that avoids limiting procedures and includes them controlled numerical dissipation. Calculations are carried out within open software package OpenFOAM is installed at ISP RAS. Unsteady flow in the pump is studied.
