Objectives and competences
During the course we will study multidimensional and dynamic heat transfer using the diffusion differential equation. First, the solutions of the diffusion equation will be obtained analytically, so that the relationship between boundary conditions, physical quantities and system response can be understood. Later, the solutions to the diffusion equation will be obtained numerically, so that real situations can be investigated, such as thermal bridges and time dependent response of a homogeneous wall. Finally, we will become familiar with the software for numerical calculation of thermal bridges.
Content (Syllabus outline)
1. Basics of heat transfer
2. Analytical solutions of the diffusion equation
3. Thermal bridges
4. Numerical solutions of the diffusion equation
5. Time dependent response of the homogeneous wall with the ad hoc method
6. Thermal properties of thermal bridges and ground with software package
Learning and teaching methods
Combination of standard lectures and practical computer work. The latter is partly carried out individually and partly in the form of group work. The Moodle platform will be used for lectures and computer work.
Intended learning outcomes - knowledge and understanding
On successful completion of this module students should be able to:
- apply analytical and numerical procedures to solve the diffusion equation
- qualitatively predict the thermal response of the building element and ground as a result of its diffusivity and effusivity
- create ad hoc software code that simulates simple dynamic heat transfer through a homogeneous wall and determine the temperature time dependence
- use software to calculate the thermal properties of thermal bridges and ground and determine surface temperatures and heat losses
Intended learning outcomes - transferable/key skills and other attributes
Problem solving strategies: indentification of underlying physical principles in engineering problems and solution formulation
