A lower bound of the invariants of the configuration tensor for some well-known differential models

Journal of Non-Newtonian Fluid Mechanics 60 (1995) 349-355


A method will be given to determine lower bounds for the invariants of a configuration tensor in 3D flows. For some well-known differential models these lower bounds will be given. Except for the Giesekus and the FENE-Pi model the lower bounds are the values in equilibrium.
