General course objectives
To build up simulation models within the CFD code Fluent for heat and fluid flow investigations in rooms and buildings, in building envelopes, in building services or in solar heating systems. It is the objective to make the participants familiar with the use of CFD in at least one of the following fields: Thermal conditions of buildings and comfort; Indoor air flow and ventilation; Wind around buildings and pedestrian comfort; Fire modeling and safety; Energy efficiency of building components and building services including solar heating systems; Optimal design of building envelops and building structures, etc.
Learning objectives
A student who has met the objectives of the course will be able to:
- Explain the principles of CFD calculations
- Formulate a CFD project on thermal conditions of buildings or wind around buildings or building services or another relevant field
- Determine the modelling goals and the scope of the CFD simulation, in consideration of time consumption and accuracy
- Build up a geometry and mesh in 2 or 3 dimensions
- Use Fluent equation solver to determine fluid flow and heat transfer
- Evaluate and use turbulence models and models for heat transfer
- Determine heat transfer and fluid flows on buildings or building services by means of CFD calculations
- Determine if CFD calculations have obtained convergence
- Analysis and presentation of calculation results
- Evaluate the reliability of heat transfer and fluid flows calculated with CFD models
