On non-Newtonian incompressible fluids with phase transitions
Descrição
A modified model for a binary fluid is analysed mathematically. The governing equations of the motion consists of a Cahn-Hilliard equation coupled with a system describing a class of non-Newtonian incompressible fluid with p-structure. The existence of weak solutions for the evolution problems is shown for the space dimension d=2 with p≥ 2 and for d=3 with p≥ 11/5. The existence of measure-valued solutions is obtained for d=3 in the case 2≤ p< 11/5. Similar existence results are obtained for the case of nondifferentiable free energy, corresponding to the density constraint psi ≤ 1. We also give regularity and uniqueness results for the solutions and characterize stable stationary solutions. Copyright © 2006 John Wiley & Sons, Ltd. http://dx.doi.org/10.1002/mma.739
