Diffusive Bejan number and second law of thermodynamics toward a new dimensionless formulation of fluid dynamics laws [PDF]
Thermal Science, 2019 In a recent paper, Liversage and Trancossi have defined a new formulation of drag as a function of the dimensionless Bejan and Reynolds numbers. Further analysis of this hypothesis has permitted to obtain a new dimensionless formulation of the fundamental equations of fluid dynamics in their integral form.

Bejan flow visualization of free convection in a Jeffrey fluid from a semi-infinite vertical cylinder [PDF]
Journal of Thermal Analysis and Calorimetry, 2019 This article studies the pattern of heat lines in free convection non-Newtonian flow from a\ud semi-infinite vertical cylinder via Bejan’s heat function concept. The viscoelastic Jeffrey fluid\ud model is employed. The time-dependent, coupled, non-linear conservation equations for\ud momentum and energy (heat) are solved computationally with the ...
