Summary

The course focuses on the theoretical and practical approaches to modelling the transport of heat. Attention is paid to the application of the theory of similarity, modelling of heat conduction in planar, cylindrical and spherical wall in case of the surface condition of 1st 3rd type and modelling of heat exchange by radiation between multiple surfaces in diathermic environment. Knowledge is applied to the modelling of heat transfer in continuous casting process.
