Simulation results for \(v\le 1.\) a The nondimensionalized Fourier-transformed normal stress change \(\widetilde{\eta }\) as a function of the nondimensional time \(s\). b \(\widetilde{\eta }\) normalized by its steady-state value \({\widetilde{\eta }}_{\mathrm{ss}}\) as a function of the nondimensional time \(s\). The thick black line shows the limit of small \(v\) (Eq. (31))
