7.6.12.44.9. Mckenzie

Syntax

Momentum Stress [{of} SpeciesName] = Mckenzie ()

Scope

Aria Material

Summary

Provides a stress tensor based on a spherical and deviatoric decomposition. The pressure is derived from the pressure of the gas phase and the divergence of the flow field. The deviatoric stress is linear in the deviatoric velocity gradient.\sigma = (1. - \phi) ((P_g -\beta \nabla \cdot v) I + \frac{\mu}{2} (\nabla v + \nabla v ^T - \frac{2}{3} \nabla \cdot v))
