Abstract: Heat transfer dissipation from a horizontal rectangular fin embedded with equilateral triangular perforations is computed numerically using one-dimensional finite element technique. The triangle bases are parallel to the fin two sides. The body of the fin is discretized into a number of subdivisions (finite elements). The number of these elements can be altered as required according to the automatic mesh generation. The heat dissipation of the perforated fin is computed and compared with that of the solid one of the same dimensions and same thermal properties. The comparison refers to an acceptable result and heat dissipation enhancement due to certain perforation. |
Keywords and phrases: perforated fin, perforated surface, extended surfaces, heat transfer enhancement. |
