| Abstract | ||
| An experimental study is made on smooth cylinder fixed between two insulated walls to investigate the effect of inclination angle of the cylinder from the horizontal on heat transfer by free convection. The cylinder was placed in the middle space with changing inclination angle of the cylinder ( 0˚, 30˚, 60˚, 90˚). Air was used as medium for heat transfer with different thermal levels ( 5,12 , 30 ,50 ,74 ,102 ,138 ) Watt. The results show that heat transfer is in the maximum in the horizontal level and it decreases when increasing the inclination angle from the horizontal, also, the results show that the insulated walls have great effect on increasing heat transfer when compared with free case. An experimental equation is given for heat transfer from cylinder with an inclination of cylinder with horizontal level (0˚– 75˚). | ||
