EMPE2500 Building Simulation Course description

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, and cylindrical 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 difference 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 capable of analysing parallel-flow and counter-flow heat exchangers by using logarithmic mean temperature differences and ε-NTU methods. 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
• 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

Emnet bygger på Byggfaglig innføring (BYFE1201), Termodynamikk (EMTS1400) og komplimenterer Varmetransport (EMTS2300) som går parallelt.

Ingen arbeidskrav eller obligatorisk aktivitet

Eksamen i emnet er en skoleeksamen på 5 timer.

Gradert skala A - F

Det benyttes intern og ekstern sensor til sensurering av besvarelsene.

Et uttrekk på minst 25% av besvarelsene sensureres av to sensorer. Karakterene på disse samsensurerte besvarelsene skal danne grunnlag for å fastsette nivå på resten av besvarelsene.

Excel og SIMIEN er tilgjengelig under eksamen. Hjelpemidler som formelark vedlagt eksamensoppgaven. Håndholdt kalkulator som ikke kommuniserer trådløst og som ikke kan regne symbolsk. Dersom kalkulatoren har mulighet for lagring i internminnet skal minnet være slettet før eksamen. Stikkprøver kan foretas.

Gradert skala A-F.

En intern sensor. Ekstern sensor brukes jevnlig.
