Nusselt number calculation
sir i have to calculate the nusselt number ratio augumentation for dimple surface and smooth surface for reynolds number for laminar flow
Nu/Nuo..plz help me 
Hi
Did you find your answer. I also worked on dimpled surface in fluent and gambit and now I am working on a code for simulating the convective heat transfer along a dimpled surface. let me know if you need help yet 
nusselt number
respected sir plz send me the formula for nusselt number augumentation for flat and dimpled surface by reynolds number are 500 750 1000 1650 respectively
plz send me the formula and cf/cfo ratio.

friction factor calulation
sir i want to calculate the friction factor for the reynolds number 500,750,1000,1650
for both the flat plate and dimpled surface. thank u
