Abstract

Two different additively manufacturable metal structures are evaluated with regard to their entropy production number. The structures are investigated at two temperature levels: 200/80 °C and 700/580 °C. At the low temperature level, the heat conduction within the structure is the main driver for entropy production. If the temperatures are raised, the total entropy production number increases sharply, where the dissipation due to fluid friction is the main cause for the losses occurring in both structures.
