Simulation results were then re-organized and plotted on the
Gsize– plane. Through least-square method, the variables a and b
of Eq. (1) were optimized as 0.76 and 0.36 (R2 = 0.996), respectively.
The resulting graphs are shown in Fig. 11. With an average error
of 5.24×10−2, these graphs represent all the simulation results
very well (it should be noted that accuracy on the grids with small
thermal share,
