Recently, Parter and Rajagopal have proved the existence of solutions which do not possess axi-symmetry. Here, we shall discuss the analogous problems which arise within the context of viscoelastic fluids. We s
In present years, the study of nanofluids has emerged as a hot topic among the researchers, because the nanoparticle contained in the fluids significantly enhances the heat transfer properties of the fluids. Particularly, rotating ows are of vital importance due to their wide range of scientific, ...

The fluids are enclosed in an annular region bounded by two rigid cylinders. The Oldroyd B-type viscoelastic fluid is considered and the outer cylinder is swirling with a uniform angular velocity. The governing mathematical equations are work out through the viscoelas...
Also, the effect of retardation ratio on the flow structure of viscoelastic fluid with the Weissenberg number being constant was surveyed. Based on our results, by decreasing the retardation ratio the flow becomes Newtonian like.Sahand Majidi
