Magnetic field parameters mathematical modelling of windelectric heater

Abstract

The paper presents the device and principle of operation of the developed and patented flow-through induction wind-electric heater. The development concerns the field of small wind-power industry. To substantiate the magnetic system's parameters of the wind-electric heater, a mockup of a gear magnetic system has been developed and the experimental studies' results of changes in electromagnetic values in the system's air gap are presented. As a consequence of solving the problems posed, a method for constructing multidimensional surfaces using the Lagrange polynomial with one variable was for the first time proposed for calculating electromagnetic quantities in an air gap of similar gear magnetic systems when constructing different powers of inductive converters of wind energy into thermal energy, as well as constructing response surfaces in multifactor experiments.
