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).

The students shall acquire basic knowledge of the use of quantitative methods in analytical chemistry. The course includes training in relevant analytical techniques and instrumentation methods for the recording and processing of measurement data. Handling of errors, uncertainty estimates and quality assurance in quantitative analytical chemistry will also be addressed.

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

• 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

The teaching is organised as lectures, exercises and laboratory instruction.

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

• 5-day laboratory course with 5 written assignments (two individual and three in groups of 2-4 students, 10-20 pages per assignment)
• Some exercise sessions related to the laboratory course will be compulsory. These sessions will be announced separately.

Individual written exam, 3 hours.

The exam result can be appealed.

In the event of a resit or rescheduled exam, oral examination may be used instead of written. If oral exams are used for resit and rescheduled exams, the exam result cannot be appealed.

A handheld calculator that cannot be used for wireless communication or to perform symbolic calculations. If the calculator's internal memory can store data, the memory must be deleted before the exam. Random checks may be carried out.

Grade scale A-F.
