This study examined hydrothermal performance in distilled water flowing in corrugated pipes in turbulent flow regime using Finite volume method in CFD code. The modified pipes are designed with three kinds of corrugation profiles (Inward, outward and Composite) and varying corrugation amplitude of the composite corrugated pipe. The smooth straight pipe, outwardly corrugated straight pipe, inwardly corrugated straight pipe and composite corrugated smooth pipe are abbreviated as S-S-P, O-C-S-P, I-C-S-P and C-C-S-P. The impact of varying amplitude and Reynolds number (Re) on average Nusselt number (Nu), Poiseuille number (fRe), performance evaluation criterion (PEC) and field synergy number were examined. The finding revealed that most of the modified pipes have higher Nu compared to straight pipe and they have substantial PEC value up to Re of 35,000. For instance, at Re = 20, 000 the (fRe), Nu and PEC values of the pipes, O-C-S-P, I-C-S-P and C-C-S-P at corrugation amplitude, 0.05 are {963.5, 1432, 1732.75}, {215.8, 221.1, and 232.2} and {1.12, 1.006, 1.0} respectively. Thus, from an energy-saving perspective, the C-C-S-P can be suggested as a promising heat transfer enhancement method than S-S-P, O-C-S-P and I-C-S-P.
