Figure 3

Figure shows on a semi-log scale the temperature mean and standard deviation as a function of time of the top surface of the silicone oil film as it relaxes to room temperature after the applied heating power is removed. The left axis corresponds to the temperature mean in degrees Celsius (solid blue circles) and the right axis corresponds to the standard deviation (solid red triangles). Plots (a,b,c) show cooling profiles for the film thickness of \({l}_{z}=4.74\,mm\), and plots (d,e,f) for \({l}_{z}=5.02\,mm\). Note that the applied heating power in Watts are labeled by the far left y–axis.
