Numerical simulation of fluid flow through an array of diamond-shaped pin fins
V. B. Grannis,Ephraim M Sparrow +1 more
TL;DR: In this article, numerical solutions for the fluid flow in a heat exchanger consisting of an array of diamond-shaped pin fins were obtained for the periodic fully developed regime, whereby the velocity field repeats itself from row to row and the pressure field also repeats periodically relative to a linear axial decrease.
