Blood at non-Newtonian workshop !!

I was attending the 14th International Workshop on Numerical Methods for non-Newtonian Flows at Santa-Fe, New Mexico. And, an important point of discussion in this workshop was that the numerical methods should be used for bio-fluid analysis.
Robert Owens, who is a professor of at the "Largest" French university in North-America, presented a new constitutive model for blood flow based on sticky-dumbells. This work seems to be an improvement on the previously proposed generalized-Newtonian (shear-thinning) Oldroyd-B type model proposed by Anand and Rajagopal (Anand2004a). The models has a closed form constitutive equations which needs to be tested for the extremities in a 3D blood flow simulations.
Further, there were some people interested in turbulence modeling for the blood and other bio-fluids.
Prof. Marek Behr presented the Galerkin Least Squares methods for the viscoelastic fluids, which is under development for high performance computing of bio-fluid and other viscoelastic fluids.
