| Abstract | ||
| This study deals with heat transfer by free convection from the outer surface of two cylinders (Triangular & Rectangular shape fined cylinder 8-fins). The experimental work was conducted with air as a heat transport medium. The cylinders were fixed at horizontal rectangular duct and fixed at different inclination angles (0o, 30o, 60o, 90o) .The heat fluxes were (279, 1012, 1958, 3005, 4419) W/m2. Where heat transferred by convection and radiation. The results show the heat transferred from the triangular finned cylinder is maximum at slop angle (30o) and minimum at the slop angle (0o) with the range from [Ra = (1.68*107 – 3.46*108)]. | ||
