| Sumario: | This report aspires to deepen in the field of Computational Fluid Dynamics (CFD) and detail the steps to convert a physical phenomenon into a solvable domain. Four parts can be clearly differenced along this thesis. First, we set basic concepts such as governing equations, numerical methods and schemes, solvers and algorithms which are essential for the resolution of any real case. Secondly, we give a brief overview of turbulence and its modelling. Then we resolve three well-known didactic exercises of forced, natural and mixed convection and compare our results to benchmark solutions. Finally, we make an introduction to Thermal Comfort and apply all previous knowledge for the study of thermal comfort inside a room. For the resolution of the exercises, we used a self-developed C++ code due to its good efficiency in resolving computationally expensive algorithms. The results obtained in the first three didactic exercises are in accordance with the benchmark solutions, and hence we conclude our code is well-implemented. The layout used in our thermal comfort case gives as a result an acceptable comfort distribution throughout the room. We recommend to take a look at future lines which provide ideas for further thesis |
