STUDY OF ENTROPY GENERATION IN A SLAB WITH NON-UNIFORM INTERNAL HEAT GENERATION

Abstract

Analysis of entropy generation in a rectangular slab with a nonuniform nternal heat generation is presented. Dimensionless local and otal entropy generation during steady state heat conduction through he slab are obtained. Two different boundary conditions have been onsidered in the analysis, the first with asymmetric convection and the econd with constant slab surface temperature. Temperature istribution within the slab is obtained analytically. The study nvestigates the effect of some relevant dimensionless heat transfer arameters on entropy generation. The results show that there exists a inimum local entropy generation but there does not exist a minimum otal entropy generation for certain combinations of the heat transfer arameters. The results of calculations are presented graphically.
