摘要：Unsteady flow of an incompressible Maxwell fluid with fractional derivative induced by a sudden movedplate has been studied, where the no-slip assumption between the wall and the fluid is no longer valid. The solutionsobtained for the velocity field and shear stress, written in terms of Wright generalized hypergeometric functions ??Ψ??,by using discrete Laplace transform of the sequential fractional derivatives, satisfy all imposed initial and boundaryconditions. The no-slip contributions, that appeared in the general solutions, as expected, tend to zero when slipparameter is ??→0. Furthermore, the solutions for ordinary Maxwell and Newtonian fluids, performing the same motion,are obtained as special cases of general solutions. The solutions for fractional and ordinary Maxwell fluid forno-slip condition also obtained as limiting cases, and they are equivalent to the previously known results. Finally,the influence of the material, slip, and the fractional parameters on the fluid motion as well as a comparison amongfractional Maxwell, ordinary Maxwell, and Newtonian fluids is also discussed by graphical illustrations.
