Abstract
This contribution deals with a modelling of the tangential velocity slip problem in terms of variational inequalities. In particular, the critical shear stress criterion is considered. The theoretical conditions under which a unique solution exists are discussed and an algebraic description based upon a complementarity approach is presented, similar to the one adopted in [7]. Finally, preliminary numerical results are presented and discussed.
