It is found that Nu value
increases with the rise of Re.
Higher NU value
means non-uniform ink coverage of the printing substrate (Stanic et al, 2008).
The third of my suggestions is called nu value in honor of the Yiddish expression "Nu?" (rough translation: So?
Nu value can of course be defined in many ways: what the seller thinks, for example, or the buyer, the lender, or the regulators, or what the neighbors say when discussing the problem over a plate of chopped liver.
The advantages of nu value over market value should be apparent: no more entanglement in questionable facts, no more hypothetical conditions, and clear answers reachable in the course of a single meeting.
The sympathetic activity and parasympathetic activity are considered as a measure of LF and LF nu power values and HF and HF nu values
power values, respectively.
For a single phase, laminar, flow through a minichannel, Nu values for porous pin fins did show improvement compared to the solid fin channel.
8 and are very similar to the value obtained in the experimental work for Nu values and pressure drop except for Re 100 and Re 500 (for pressure drop alone) within 8.3-32.8%.
* [Al.sub.2][O.sub.3]/[H.sub.2]O nanofluid in comparison to the minichannel containing no nanofluid and pin fins as solid and porous medium recorded 88% and 77% higher Nu values. The associated pressure drops are seen decreased; but in reverse magnitude.
* Both [Al.sub.2][O.sub.3]/[H.sub.2]O and CuO/[H.sub.2]O nanofluids registered a 38% higher Nu from 0.001 to 0.01% volumetric concentrations and then decreases at 0.1 and 1% volumetric concentrations so that there exist no significant difference in Nu values at 0.001 and 1% volumetric concentrations.
Circular cross-section ducts present the least Nu values
till Re = 250, while Shape-2 cross-section ducts present the highest Nu values
after Re = 250.
