AB - <p style="text-align: justify;">This paper considers the unsteady boundary layer flow over a moving flat
plate embedded in a porous medium with fractional Oldroyd-B viscoelastic
fluid. The governing equations with mixed time-space fractional derivatives
are solved numerically by using the finite difference method combined with
an L1-algorithm. The effect of various physical parameters on the velocity
and average skin friction are discussed and graphically illustrated in detail.
Results show that the porosity $ϵ$ and fractional derivative $α$ enhance the flow of
Oldroyd-B viscoelastic fluid within porous medium, but fractional derivative $β$ weakens the flow. Moreover, it is found that the average skin friction coefficient
rises with the increase of fractional derivative $β.$</p>
