[(a) and (f)] Time-averaged flow field. (a) Case 1, Strain%=35.94, $\dot{Q}=0.3\times {10}^{-3}{\mathrm{m}}^3∕\mathrm{s}$. (b) Case 2, strain %=35.94, $\dot{Q}={10}^{-3}{\mathrm{m}}^3∕\mathrm{s}$. (c) Case 3, strain %=40.18, $\dot{Q}=0.217\times {10}^{-3}{\mathrm{m}}^3∕\mathrm{s}$. (d) Case 4, strain %=40.18, $\dot{Q}={10}^{-3}{\mathrm{m}}^3∕\mathrm{s}$. (e) Case 5, strain %=43.57, $\dot{Q}=0.2\times {10}^{-3}{\mathrm{m}}^3∕\mathrm{s}$. (f) Case 6, strain %=43.57, $\dot{Q}={10}^{-3}{\mathrm{m}}^3∕\mathrm{s}$.
