A lot of research was done in the past about the importance of good indoor climate for health and well-being. Indoor air quality as well as thermal comfort are impacted by mechanical ventilation. Several different mechanisms for mechanical ventilation are known, such as forced convection, natural convection, or Coanda effect. The goal is to obtain a validated numerical model of several different mechanical ventilation systems within the CFD software ANSYS Fluent. The model must be validated using experimental data gathered inside the climate chamber of the department of Building Physics. For this, the chamber shall be equipped representing an office setup with a workstation and a thermal manikin. The experimental data is used to find the most appropriate calculation model for the simulations. Tasks: - Literature research - Measurements in the climate chamber of the department of building physics - Setup of the numerical model in ANSYS Fluent incl. geometry & mesh generation - Validation of the numerical model - Simulation of different ventilation systems - Analysis of the indoor air quality and thermal comfort |
