Non newtonian visco-elastic OLROYD-B model for lubrication
Résumé
Following the well known asymptotic approach, we study the limit of the equations describing an OLroyd-B visco elastic mixture with lubrication assumption . We prove that the limit thin flow is well described by a specific Carreau Yosida law.: The double Newtonian shear thinning Rabinowisn law.
