Flow Analysis Heat and Mass Transfer in a Room


, Isfahan University of Technology


This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k-  turbulence model was employed. By means of SIMPLE algorithm the system of eight equations are solved. From the flow field solution the velocity vector plots, temperature and contamination contour plots were obtained and the results are compared with the calculated and published results. Agreement is reasonable enough and the results of such a study would help in much better use of indoor areas. Also it would be possible to estimate the heat load and the contamination removal from a room more accurately.
