Webwhere τ is the shear stress, K is the flow consistency index, γ is the shear rate, and n is the flow behavior index. The larger the deviation of n from 1, the more non-Newtonian is the behavior of the fluid. For a Newtonian fluid, n is equal to 1; for a dilatant, n is greater than 1; for a pseudoplastic fluid, n is less than 1 [2,3]. WebMar 29, 2016 · The technique of nonlinearity ramping can be applied in many different ways. For instance, instead of viscosity ramping, we can ramp the gravitational force in natural convection problems or the flow behavior index “n” in non-Newtonian fluid flows. It can also be used more generally in any nonlinear multiphysics problem, as highlighted here. immunotherapy for cancer youtube
