In a single-pass U-type counterflow PHE, three different chevron plate arrangements are considered: two symmetric plate arrangements with beta = 30 deg/30 deg and 60 deg/60 deg, and one mixed-plate arrangement with beta = 30 deg/60 deg. For water (2 < Pr < 6) flow rates in the 600 < Re < 104 regime, data for Nu and f are presented. The results show significant effects of both the chevron angle beta and surface area enlargement factor phi. As beta increases, and compared to a flat-plate pack, up to two to five times higher Nu are obtained; the concomitant f, however, are 13 to 44 times higher. Increasing phi also has a similar, though smaller effect. Based on experimental data for Re a 7000 and 30 deg <= beta <= 60 deg, predictive correlations of the form Nu = C1,(beta) D1(phi) Rep1(beta)Pr1/3(µ/µw)0.14 and f = C2(beta) D2(phi) Rep2(beta) are devised. Finally, at constant pumping power, and depending upon Re, beta, and phi, the heat transfer is found to be enhanced by up to 2.8 times that in an equivalent flat-plate channel.
