Aim
The course aims to provide deeper knowledge, a wider scope and improved understanding of the mechanisms of heat and mass transfer as well as a better insight into analytical and empirical methods applied in analysis and synthesis of heat and mass transfer related problems. The students should gain knowledge to apply the theories to relevant engineering problems. The course is a continuation and extension of the basic heat transfer course MMV031 Heat Transfer.

Knowledge and understanding
For a passing grade the student must

• understand the basic concepts of heat conduction, convection, optimization of heat exchanger network, diffusion/convection mass transfer with and without chemical reactions.

• explain the important and basic ideas of the subject

• describe the physical mechanisms of the heat and mass transfer from relevant technical problems.

• describe various types of analytical and empirical methods by consideration of physical background, assumptions and applications for different problems.

• describe and explain analysis and synthesis methods for temperature and concentration, heat and mass transfer.

Skills and abilities
For a passing grade the student must

• be able to actively participate in discussions concerning relevant heat and mass transfer problems.

• be able to in oral and written ways present analyses and results of temperature and concentration fields, etc.

Judgement and approach
For a passing grade the student must

• be able to analyze the physical problems and formulate general equations for heat transfer, energy equation, combined heat and mass transfer.

• be able to apply analytical/empirical methods or propose numerical methods for heat and mass transfer problems.

• be able to evaluate and estimate the realibility of results for heat and mass transfer problems.

Contents
Periodic heat conduction, melting-/solidification, permeable materials, anisotropic materials. General energy equation, heat transfer at high velocities, heat transfer in rarefied gases and porous media. Optimization of heat exchanger networks with respect to heat recovery (pinch technology). Grassroot design, retrofit design, and introduction of heat pumps are exemplified. Diffusive mass transfer in solids, convective mass transfer and combined heat and mass transfer. Mass transfer with and without chemical reactions (combustion) is illustrated. Introduction of the radiation transfer equation (RTE) for handling participating media like gases and liquids. Transport phenomena in fuel cells like momentum, mass, energy transports as well as chemical reactions, and numerical simulation methods.

Literature
The course literature consists of excerpts from the international literature, compendia material, and computer software for the pinch technology.
