Natural convection heat transfer from a cylinder suspended in water at different tilting angle has been analyzed numerically by varying the Rayleigh number (Ra) in laminar regime (104 ≤ Ra ≤ 108). The numerical analysis is carried out at different tilting angles in the range from 0 to 90 from vertical position using Ansys 15.0- Fluent computer code. The temperature and velocity contours as well as average Nu and surface temperature have been obtained at different Ra for each tilting angle. It has been found that the average Nu increase while the average surface temperature decrease with the increase in Ra for all of the cases. By increasing the tilting angle from the vertical position, the average Nu increases whereas the average surface temperature decreases until a tilting angle of 45o. Further increase in the tilting angle results in decrease in the average Nu, whereas average surface temperature changes slightly. A unique correlation relating Nu with Ra for natural convection from cylinder inclined at any arbitrary angle was developed.
