This study deals with heat transfer by free convection from the outer surface of twocylinders (Triangular & Rectangular shape fined cylinder 12-fins). The experimentalwork was conducted with air as a heat transport medium. The cylinders were fixed atdifferent slope angles (0o, 30o, 60o, 90o) .The heat fluxes was (1310, 837, 470, 212, 53)W/m2. Where heat transferred by convection and radiation. The results show that heattransfer from the triangular finned cylinder is maximum at a slope angle (90o) andminimum at the slope angle (0o) with the range from [Ra = (1.54*107 – 1.57*108)].
