Figure 2From: Rotational motion of fractional Maxwell fluids in a circular duct due to a time-dependent coupleProfiles of the shear stress \(\tau (r,t)\) and the velocity \(w(r,t)\) given by Eqs. (22) and (25), respectively, for \(R=1\), \(g=2\), \(\eta =0.45\), \(\nu =0.2\), \(t=7\), \(\rho =800 \), and different values of λBack to article page
