| Abstract | ||
| This study deals with heat transfer by free convection from the outer surface of two cylinders (Triangular & Rectangular shape fined cylinder). The experimental work was conducted with air as a heat transport medium. The cylinders were fixed at different slope angles (0°, 30°, 60°, 90°) with heat dissipation of (33820, 21751, 12335, 5570, 1459) W/m². In an open medium to the atmospheric air where heat transferred by convection and radiation. The results show that heat transfer from the triangular finned cylinder is maximtun at a slope angle (90°) and minimum at the slope angle (0°) with the range from [Ra (2.543*10-1.5098*10")]. | ||
