In this dissertation a detailed comparision between the simulation (CFD) and experimental technique was done in an air conditioned room in order to analyze the incoming air flow pattern and to improve the quality of air which is coming inside the room. An experiment is performed in the workshop of LNCT Bhopal, to find out the air flow pattern and its distribution through different swirl diffuser having different slot angle, installed at the ceiling in an air conditioned room. It is basically performed to evaluate the thermal comfort produced in a room equipped with a heat load of 1500W load capacity with different swirl diffusers and compare their performance graphically. My project is to do the same project but with a different technique i.e CFD (Computational Fluid Dynamics) and to compare the results which has come out from the experimental with the results that is coming out from the CFD. A set up mainly consist of a woode n room of size 4ft X 4ft X 5ft with different models of swirl diffusers installed at the ceiling level. The air supplied from an air conditioner through a swirl diffuser which is placed at the bottom. There are six different location at the floor inside th e room where reading is to be taken of temperature and there variation with respect to height. There are six locations at floor i.e X1,X2,X3,Y1,Y2 and Y3. The result from this desertation work is that the simulation technique (CFD) gives more accurate and consistent result as compare to the experimental technique. Velocity distribution inside the room and the graphs are plotted at six different locations inside the room, which shows the comparision between Experimental  and CFD technique. In this disser tation work it is analyzed that the experimental technique is time consuming and also the results are also not consistent so it is beneficial to use the simulation technique in case of flow analysis.
