The singularity near a re-entrant corner of Oldroyd-B fluid has been studied in the literature, at least for re-entrant corner γ=270 o . It was shown that, except near, the walls, the flow develops singularities which are self-similar, very much like the Newtonian singularities. This paper considers the case of a general Oldroyd model and a general re-entrant corner. Under some assumptions...
