Fig. 10: Measured apparent viscosity as a function of time.

a for a strong excitation impulse exhibiting overshoot decay behavior pattern, and (b) for a moderately low excitation impulse exhibiting free decay behavior pattern, both as a function of relative time after pulse application and superimposed on the decreasing temperature profile. c Normalized viscosity as a function of time at various Taylor–Reynold’s numbers showing the overshoot and free decay pattern transition. d Critical impulse limitation to avoid overshoot delay and the timescale of the decay period.
