The ephemeral nature of Navier–Stokes-$\alpha \beta$ continua

Abstract

Navier–Stokes-$\alpha \beta$ continua are shown to be a special subclass of the recently introduced class of ephemeral continua that arises when particular constraints and constitutive relations are introduced. Beside offering a new endorsement of balance equations already obtained by numerous Authors, our study offers a chance for enlightening remarks, remarks that might possibly lead to further developments.
