... not contain any fin geometry parameters betrays that its leading constant is compensating for this. For this reason, Eq. (3) is valid for only the present fin geometry and; in addition, it does not have an asymptote of N np / A s at large heat flux as it should. Nevertheless, Eq. (3) is simple...

.... In addition, fairly good absolute agreement was achieved between measurements and predictions for each nanolubricant mass fraction. For example, the heat flux ratios for the (99.5/0.5) mixture and the (98/2) mixture were overpredicted, on average, by roughly 5% and 26%, respectively. Similarly, the (99/1...
