A MODIFIED DECOMPOSITION SOLUTION OF TRIANGULAR FIN WITH TEMPERATURE DEPENDENT THERMAL CONDUCTIVITY AND HEAT GENERATION

In this paper, we propose, the modified decomposition method (MADM) is a recent mathematicaltechnique for a closed form solution of nonlinear heat transfer equation of a longitudinal triangularfin where the thermal conductivity and internal heat generation are temperature dependent. Theenergy balance equation of triangular fin with the temperature dependent thermal conductivity andinternal heat generation is solved by MADM. The results obtained from the MADM are comparedwith the differential transform method (DTM). The effects of the various thermo physicalparameters, such as convective-conductive parameter, heat generation number, and convective sinktemperature on the dimensionless temperature distribution, are analyzed comprehensively.
