Appendix Good:: Extension to help you Nonlinear Viscosity
The worries rate inside, eg inside the (3), could possibly get trust deviatoric worry to the nth power. My derivation carries by way of when (3) can be so altered [ Sleep, 2011 ]. Nonlinear convection which have shear is challenging since associated worry is actually the following invariant of the stress tensor , and therefore highly lovers convection that have shear. We qualitatively talk about the three topics away from my report.
The derivations apply using (7) to obtain the dependence on T?, providing that ?down is understood to be an effective nonlinear viscosity.
My derivation of scalloping involves forces and flow at the apex of upwellings. Qualitatively, the thicker rheological boundary layer at high n from (7) suppresses scalloping at given T?. Formally, the pressure term in (25) may be modified to ?P n and N replaced with N/n in (26) and (27). Numerical calculations are necessary to obtain a calibrated expression analogous to (28).
Alignment of convection into rolls by plate motions does not appear to be strongly dependent on nonlinear viscosity. van Hunen and Zhong presented numerical calculations with results similar to those of their linear viscosity cases. (more…)
