Anotation:

The definition of fundamental equations of heat and mass transfer in electromagnetic field in continuum. Thermal effects of electromagnetic field. The definition of the problems of induction, dielectric and arc heating. Similarity and analogy of equations and their use. Numerical methods in electroheat.

Content:

This course deals with physical laws of thermodynamics, heat transfer, mass and energy transfer relevant for electrical heating devices design. Special emphasis is put on theoretical and practical heat transfer (conduction, convection, radiation). Results of theoretical treatment are shown using practical examples from nowdays design of electroheat devices.

Course outlines:

1. Physical foundations of electrical heat
2. Mathematical apparatus of the continuum
3. Physical foundations - momentum transfer, continuity equations
4. Fourier-Kirchhoff heat transfer equation
5. Heat transfer - Convection, Criteria definitions
6. Radiative Heat transfer - Planck's law, Kirchhoff's law
7. Radiative Heat transfer - solutions using configuration factors
8. The problem of direct resistive heating
9. The problem of indirect resistive heating
10. The problem of induction heating of non-ferromagnetic materials
11. The problem of ferromagnetic material heating,
12. The problem of dielectric and microwave heating
13. Mathematical models of an electric arc
14. Reserve
