HEAT TRANSFER | MMV031 |

**Aim**

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.

*Knowledge and understanding*

For a passing grade the student must

- describe the fundamental mechanisms for heat transfer
- explain the basic and important properties of the subject
- perform analysis and synthesis of problems in heat conduction, convection, thermal radiation, condensation and evaporation
- understand the basic heat exchanger theory
- explain and analyse internal and external laminar and turbulent heat transfer
- understand under what conditions analytical or empirical methods are applicable

*Skills and abilities*

For a passing grade the student must

- analyse different heat transfer problems and suggest methods for analysis and synthesis
- judge the uncertainties in the magnitude of heat fluxes and heat transfer coefficients
- critically review chosen methods and results of calculations of heat transfer problems
- participate in discussions and judgement of relevant problems of heat transfer
- to present analysis and synthesis of basic questions of heat transfer both in a wriiten way and orally

**Contents**

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.
