Abstract
When a second law analysis is applied to a heat transfer process, the influence of boundary conditions on the chosen assessment criterion is of major importance. In this paper, three different sets of boundary conditions and three different assessment criteria based on the entropy generation are applied to a plate heat exchanger. The influence of the boundary conditions on the device’s operation and on the usefulness of the assessment criteria is discussed.
