Subject aims expressed by acquired skills and competences

- the student will be able to apply the dimensional analysis to solve engineering problems, - the student will be able to solve analytically or numerically difficult problems of heat transfer by conduction and convection, - the student will be able to apply theoretical methods to solve the heat exchange by radiation between multiple surfaces, - the student will be able to describe and analyze ways of heat transport in the continuous casting.

Teaching methods



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.
