Dynamic subscales and unconditional semi-discrete stability for non-residual VMS approximations of generalised Newtonian flows

We analyse a non-residual variational multiscale finite element formulation with dynamic subscales for incompressible generalised Newtonian Navier--Stokes flows. The apparent viscosity is assumed to be bounded and Lipschitz continuous with respect to the shear rate, covering several regularised rheological laws. The me...
