AB - A new definition of Bejan number will be generated by replacing the thermal  diffusivity with the mass diffusivity. For example, the Schmidt number is the  mass transfer analog of the Prandtl number. For the case of Reynolds analogy  (Sc = Pr = = 1), both current and new definitions of Bejan number are the  same. This new definition is useful and needed for diffusion of mass (mass  diffusion).
