From the Extremum Principle of Entransy Dissipation to Steady Balance Equations of Fluid Mechanics

In the present work, an extremum principle of entransy dissipation is developed by taking into account the contribution of fluid friction. It is found that this extremum principle of entransy dissipation leads to the same balance equations as given in continuum mechanics for the steady heat conduction and shear flow in an incompressible fluid.
