Abstract

In the current study, the investigation of heat transfer and fluid flow Characteristics of Pure water when pass through a triple tube heat exchanger (CTTHX). this investigation has been conducted across various Reynolds Number to gain insights into their performance also conducted a computational fluid dynamics (CFD) simulation using the ANSYS-FLUENT software. Result obtained was validated by comparing to empirical correlation data found in the existing literature. The investigation considered various operating variable as Reynolds Number and temperature across the inner, intermediate, and outer tubes. Specifically, the Reynolds Number of 2000 at 305 K, a range of 2000 to 4500 at 340 K, and 2000 at 295 K for the respective tubes. Key findings are that friction factor increase by 12.5% as compared to correlation in existing literature. And Nusselt number (Nu) increase by 50% in the range of Reynolds Number (Re) from 2000 to 4500.
