one-dimensional flow

19, 20], the existence of periodic solutions in the linearly unstable regime is demonstrated in the case of the one-dimensional flow, without the use of periodic conditions in the direction of the flow.
The above models, which assumed that only one significant flow exists in each control volume, were called one-dimensional flow models.
Some models apply the well-known lubrication approximation to both the cavity(s) and slot(s) of a die (1-9); some models use a one-dimensional flow model, which includes the inertia and gravity terms, in the cavity(s), and the lubrication approximation in the slot(s) (10-12); some models solve the two-dimensional flow inside the slot(s) (13-15); and some models use a three-dimensional numerical approach (16, 17).
The truncated power-law model, in which the power-law model is terminated at the limiting Newtonian viscosities, has been applied to this situation without sacrificing the power-law equations for one-dimensional flow [5, 10, 11].
