$D_{\mathrm{eff}}{}^{*}$ $\varphi =0.08$ suspension obtained using flow compensated PGSE sequence [inset in (a)], which measures only irreversible stochastic motions. (a) For an average velocity of $0.88\mathrm{mm}/\mathrm{s}$ (${\mathrm{Re}}_p=7.3\times {10}^{-6}$, ${\mathrm{Pe}}_p=39$) $D_{\mathrm{eff}}{}^{*}$ for the particle core oil as a function of observation time $\Delta$ in the flow direction $z$, $D_{zz,s}{}^{*}$ (black closed circles), in the velocity gradient direction $y$, $D_{yy,s}{}^{*}$ (green closed triangles), and in the absence of flow in the $z$, $D_{zz,s}{}^{*}$ (black open circles) and $y$, $D_{yy,s}{}^{*}$ (green open triangles) directions. (b) $D_{\mathrm{eff}}{}^{*}$ normalized by the average shear rate $⟨\dot{\gamma }⟩$ and the square of the particle diameter $4a^2$ as a function of accumulated strain $\gamma =⟨\dot{\gamma }⟩\Delta$.Reuse & Permissions
