  • 0017-9310
Subject(s): Online resources: In: International Journal of Heat and Mass TransferSummary: Increasing the heat dissipation of annular fins at a denned magnitude of mass is the problem considered in this paper. Four different cross-section shapes are examined—constant thickness, constant area for heat flow, triangular and parabolic fin shapes. The fin efficiency together with the optimized dimensions are presented, which enables the design of the best fin for any practical use.
