Performance of Pin Fin Cast Aluminum Coldwalls, Part 1: Friction Factor Correlations

At low to moderate Reynolds numbers, cast pin e n coldwalls provide the best performance and lowest unit cost when castings are economically viable. An extensive literature search revealed that, although signie cant research has been done for relatively short pin e ns (L/d 10 3 , the friction factor is independent of pin length and Reynolds number.
