Transient 3-D Modeling of Ceiling Fans using CFD for Achieving Thermal Comfort

In this study, our aim is to check, compare and validate the 3-dimensional transient model of a ceiling fan using Computational Fluid Dynamics. This is done by comparing the experimentally measured values with simulated values of air velocities at various precisely located points, in a building envelope, for achieving thermal comfort, using ceiling fan by ANSYS 18.2. As, the flow of air originating from fan is having turbulent nature and there are so many models available, so choosing the correct model is necessity. In this study, the comparison of the experimental work is done for the four most widely used turbulence models i.e. the standard k- ω, the SST k-ω, the standard k-ε and the Realizable k-ε. After the analysis and comparison it was found that the result obtained from the SST k-ω are best suited to model for this type of problem, as the simulated values thus obtained shows agreement of 94% with the experimented values.
