Abstract: With the JohnsonSegalman (JS) model as a model of the shear flow of polymeric fluid, we proved that unsteady solution is bounded and presented a priori estimation in Sobolev norm and an upwind scheme with ε=0 for the model.

Key words: priori estimation, an upwind scheme, JohnsonSegalman fluid
