Analysis of Exergetic Losses in Heat Conductivity Processes.

Based on thermodynamics of irreversible processes, expressions are obtained making it possible to calculate exergetic losses in simple-shaped bodies with and without internal heat sources. The process of thermal conductivity with minimal exergy losses is analyzed. For simple-shaped bodies, temperature distributions, heat fluxes on their surfaces, and distribution of internal heat sinks, ensuring minimal losses, are obtained. This analysis is illustrated by numerical calculations.
