To Investigate the Convective Heat Transfer Coefficient Using Nanofluid in a Right Angled, Triangular Shaped Corrugated Tube for Turbulent Flow

Abstract

The fluid dynamics programme ANSYS Fluent, which is available commercially, is used to perform a numerical study of turbulence-forced convective flow through a right-angled, triangular-shaped corrugated tube. The impact of the Reynolds number on the convective transfer of energy and the loss of pressure was examined using numerical simulations for turbulent nanofluid flow within a tube with a constant flow of heat on the wall. In this research, a right-angled triangular-shaped corrugated tube is used to test the turbulent flow of many nanofluids, including Al2O3, TiO2, and CuO. (Reynolds numbers 5,000–25,000). To solve the equations that govern the system, a technique that makes use of finite volumes is employed. According to the findings, the coefficient of heat transfer improves as both the Reynolds number and the volume percent of the nanofluid increase. The nanofluid densities of TiO2-water are 27.35%, Al2O3-water is 44.66%, and CuO-water is 25.75% at a 5% volume fraction and a Reynolds number of 25000.
