You thought I didn't have competing men in my life? Well, that is not true. I have two of them.
Garimella and Thome (pronounced toe-mae or something like that).
Who are these men, you ask?
Ah, they are article writers.
Garimella has written some of the most useful work on condensation heat transfer in microtubes. He is referenced all over the place. He uses fluid-to-fluid heat exchangers which give one at best about 40% uncertainies. But he's gotten the best uncertainties out of them than most other people.
Thome writes about boiling heat transfer and bubbles. I actually found an article of his about condensation too. But it was mostly about bubbles. Bubbles in the microchannels as the refrigerant he is studying condenses or boils. I read his work too to learn more about watching fluids flow through tubes.
Garimella has also done some fluid flow visualization (fancy words for taking pictures of a fluid running through a glass or other see-through tube). Thome uses microchannels in silicon or other things like that with pieces of pyrex (type of glass) so he can see the fluid flow. Garimella uses long tubes of glass with very small diameters so he can see the fluid flow. Actually, Garimella uses glass tubes inside plastic or acrylic tubes. It keeps the glass tube from breaking when the fluid flowing through has a high pressure.
Hum, I don't know which I like best though. And this why they are the two competing men in my life.
