ENTROPY GENERATION IN A STEADY STATE HEAT CONDUCTION: A STUDY FOR THE PLANE WALL
Abstract
In technical applications, there are many processes developed at high temperatures. Loss of heat to the surrounding represent a loss of energy, an important task of engineers being to minimize heat losses. In all types of heat transfer processes, thermodynamic irreversibility is associated with entropy generation, which results in the destruction of available work. In a pure heat conduction process, the generation of entropy is the result of heat transfer through a finite temperature difference. This paper investigates entropy generation during onedimensional steady state conduction through a plane wall. Are considered two situations: uniform thermal conductivity without additional internal heat source and uniform thermal conductivity with additional internal heat source. For the both situation will be discussed the temperature distribution in the plane wall. Keywords
