摘要：

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 Prandt1 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).
