Syfte

The course aims to provide the students knowledge and understanding concerning the mechanisms of heat transfer and the methods, analytical and empirical, which are used in the heat transfer subject to determine the amount of heat being transferred and the temperature field. The students should reach ability to apply the theory on engineering problems.

Kursinnehåll

The course covers heat conduction, convection, thermal radiation, condensation, evaporation and heat exchangers. For heat conduction the general theory, extended surfaces and transient heating and cooling processes are included. For the convective heat transfer the basic equations, similarity laws, forced and natural convection are included. Laminar as well as turbulent cases are studied in internal (ducts) and external (tubes, immersed bodies) flows. Thermal radiation covers general theory, black and non-black bodies, grey bodies, view factors, radiative exchange between non-black surfaces as well as gas radiation. The chapter on condensation presents the basic theory on film condensation and influence of essential parameters and the geometry. Introduction to dropwise condensation is provided. The chapter on evaporation concerns boiling, empirical results, two-phase flow and heat transfer, convective boiling and condensation in tubes. The heat exchanger chapter describes various types of heat exchangers in engineering applications, presents theory and methods for sizing and rating of heat transfer equipment.
