Abstract:
One of the most fundamental needs for the mankind is fresh and clean air. It has been estimated that people spend comparatively more time in indoor premises as compared to time spent in outdoor. That created and elevated need for high-quality ventilation systems in buildings. Ventilation is necessary to remove indoor-generated pollutant by diluting these to an acceptable level and to maintain circulation of air by inducing entry of fresh air.
The objective of this thesis is to investigate air flow, contaminant flow and thermal affects in a control panel room connected with a rest room.
To study all aspects as stated above a model is developed and solved using Computation Fluid Dynamics software on a computer.
The commercial Computational Fluid Dynamics (CFD) code PHOENICS, developed by Cham, Version-3.6.1 is used to simulate the model. Laminar and turbulent models are used in simulating the flow in rooms.
Vector and contour plots of velocity, pressure, temperature and contaminant flow are studied. Comparison of laminar model and k-E model is carried out and found that there are no significant differences between the results of two models under consideration.
