EMTS2300 Heat Transfer Course description

The course aims to give the student an introduction to heat transfer and basic understanding of heat transfer processes. Practical application areas include design of components in heating and cooling systems (e.g. heat exchangers), calculation of the heating requirements of buildings and analyses of thermal comfort for people. The course builds on knowledge acquired in the courses EMTS2200 Fluid Mechanics and EMTS1400 Thermodynamics for Energy and Environment. In order to carry out more accurate and extensive/complex calculations, computer-aided Computational Fluid Dynamics (CFD) analyses are currently used. Voluntary computer lab exercises are therefore offered (MATLAB programming and CFD simulations with commercial tool).

No requirements above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student:

• has acquired an understanding of the key concepts of heat transfer, as well as the principles of the various heat transfer modes
• is familiar with and is capable of determining the heat conduction equation (three-dimensional, transient) with boundary conditions and initial conditions
• is familiar with stationary heat conduction (one and two-dimensional) in Cartesian, cylindrical or spherical coordinates
• is capable of addressing internal heat sources and use of thermal networks
• is familiar with transient (non-stationary) heat conduction, and is capable of solving simple problems (Lumped system, zero dimensional)
• is capable of using computational methods of calculating heat conduction (one, two or three dimensional, transient), using the finite volume (control volume) method
• masters explicit and implicit formulation of transient problems
• is able to calculate external and internal forced convection, addressing boundary layers and drawing velocity and temperature profiles. Empirical correlations are used.
• is familiar with natural (free) convection
• is capable of analysing parallel-flow and counter-flow heat exchangers by using logarithmic mean temperature differences. Familiar with fouling
• has insight into simple radiation physics and thermal radiation between solid surfaces. Black/grey surfaces are considered

Skills

The student is capable of:

• carrying out necessary calculations for engineering analysis of heat transfer in real-life structures, including buildings and heat exchangers, and elsewhere
• calculating heat conduction in solid elements, for example in walls (heat flow and temperature profiles)
• calculating convective heat transfer (convection) between a solid element and a fluid, both forced and natural convection
• calculating heat transfer between solid surfaces caused by thermal radiation
• calculating heat transfer between hot and cold fluids in heat exchangers

General competence

The student is capable of:

• contributing to the work of developing new technology on the basis of an understanding of mathematical modelling and //solving physical problems
• solving interrelated problems linked to heat transfer, thermodynamics and fluid mechanics. This will form a basis for calculating the power requirements and energy needs of a building etc.
• assessing whether calculation results are reasonable

Lectures, individual calculation exercises, computer exercises, laboratory exercises

The following coursework is compulsory and must be approved before the student can sit the exam:

• 8 of 12 calculation exercises
• 2 lab assignments in groups
