Abstract
Purpose: The purpose of the is to develop an algorithm for an integrated approach to solving combined multiphysical problems using the example of a multifunctional electrical device.
Design/methodology/approach: The article considers an electromechanical AC converter based on an asynchronous machine. The electromagnetic calculation was performed using the ELCUT software package. The solution of the problem of hydraulic calculation taking into account the heat transfer is related to the equations of energy, heat transfer, motion, continuity, and also the initial and boundary conditions.
Findings: An algorithm for CFD modeling of the heat and mass transfer process was developed, which includes three successive stages. The basic theoretical provisions of the associated electromagnetic, thermal, and hydraulic calculations are given. The electromagnetic calculation is based on the Maxwell equations implemented in the Elcut program. In solving the problems of hydrodynamics, a three-layer model of the Schlichting turbulent flow is used. The calculation of the average heat transfer was performed using the generalized dependence in the form of a modified Nusselt criterion.
Originality/value: The results of CFD modeling of the fluid velocity field in heat transfer and mass transfer zones allow us to design highly efficient combined energy converters.
