First general solutions for unsteady unidirectional motions of rate type fluids in cylindrical domains

The dimensionless velocity field corresponding to the motion of an Oldroyd-B fluid between two infinite coaxial circular cylinders induced by the outer cylinder that rotates around its symmetry axis with an arbitrary time-dependent velocity is determined using the integral transforms technique. The...
