It is found thatmaximum air temperature and maximum volume flow rate was 101.7oC, 306.3m³/h respectively at heat flux,500 W/m2; inclination angle; 90o and chimneythickness; 0.2m. Maximum outlet air velocity was 0.488 m/s at chimneythickness; 0.1m, heat flux; 500 W/m2; and inclination angle; 90o. Increase in heatflux, inclination angle and chimney thickness leads to increasing of volume flowrate. Increase in chimney cross-sectional area leads to decrease in air velocity andincrease in volume flow rate
