POTENTIAL CAPACITY DISSIPATION MINIMIZATION AND ENTROPY GENERATION MINIMIZATION IN HEAT CONDUCTION OPTIMIZATION

Two methods in the heat transfer enhancement, the entropy generation minimization and the potential capacity dissipation minimization, are compared by the heat conductivity optimization in volume-to-point problem. The numerical and analytic results show that the heat transfer rate obtained by potential capacity dissipation minimization is better than that by entropy generation minimization. The comparison shows that potential capacity dissipation minimization is to maximize the heat transfer rate, while the entropy generation minimization is to minimize the loss of available energy.
