Analysis of Thermal Conditions within the Flow Conduits of MHD-Devices

Abstract:

The paper presents an experimental and theoretical approach to the modeling of non-stationary thermal processes in the elements of MHD-devices. The theoretical part of the approach is based on a mathematical formulation of the non-stationary heat conduction problem and its numerical implementation by the finite-element method. The experimental part involves a series of preliminary and verification tests. A comparison of the results obtained in these experiments with the calculated data allowed us to specify heat conduction coefficients and to pick up space-time parameters of the algorithm to ensure a high degree of adequacy of mathematical description of thermal fields. The approach made it possible to set the process conditions under which the necessary level of preliminary heating of a conduit of the MHD-pump can be achieved without loss of its mechanical strength.
