Comments on 'New insight into the definitions of the Bejan number'

摘要

These notes aim to increase the awareness of the concept of Bejan Number among the readers of International Communications in Heat and Mass Transfer. They refer to the paper of Zimparov et al. because the authors, in their outstanding commentary on Bejan number neglect both the possible confusion which may arise between Hagen Number and Bejan number and the more recent outcomes which opens a new direction for future research.
