Simple correlation equations for optimum design of annular fins with uniform thickness

A model on the basis of analytics for computing maximum heat transfer in porous fins

“…Jany and Bejan [4] investigated the optimum shape for straight fins with temperature dependent thermal conductivity. Arslanturk [5] prescribed simple correlation equations for optimum design of annular fins with uniform cross section. In the optimization analysis, the fin volume was taken as fixed to determine dimensionless geometrical parameters of the fin with maximum heat transfer rate.…”

An ease of analysis for optimum design of an annular step fin

“…Under dehumidifying surface conditions, an analysis had been carried out by Kundu and Barman [8] on annular fin assembly of trapezoidal profiles to determine fin performances and optimization. Optimization of space radiators having step fins has been analyzed by Arslanturk [9]. Thermal analysis of annular fins with rectangular, trapezoidal and step profiles was performed in three publications [10][11][12].…”

Exact Analytic Heat Transfer from an Annular Fin with Stepped Rectangular Profile

“…One possibility is to relate the optimum thickness and the optimum length to the mean convection heat transfer coefficient and the thermal conductivity of the material. Representative references of this effort are those by Jakob (1949), Brown (1965), Ullman and Kalman (1989), Heggs and Ooi (2004) and Arslanturk (2005). A second possibility is to cover the annular fin of rectangular profile with a thin layer of material with a very high thermal conductivity, so that the effective thermal conductivity of the substrate/coating is aggrandized.…”
