Nanoparticles hydrothermal simulation in a pipe with insertion of compound turbulator analyzing entropy generation

摘要

The aim of this investigation is to investigate the H2O turbulent flow according to the nanoparticles, including copper oxide within a pipe outfitted by an innovative swirling flow generator. For the purpose of determining width effect in turbulent flow for Reynolds number, the results are analyzed. Moreover, relationships are obtained to estimate the irreversibility component. It is observed that viscous reduces directly proportional to pumping power. This means that following an increase in inlet velocity, differential pressure rises. Because of higher velocity gradient, by increasing width S-gen,S-f becomes greater. As turbulator with larger b is used, stronger turbulence intensity will be generated. (C) 2019 Elsevier B.V.
