ENERGY, ENTROPY AND EXERGY ANALYSES OF HYBRID NANOFLUID FLOW IN A TRAPEZOIDAL CHANNEL

This study presents energy, entropy, and exergy analyses of Al2O3-Cu/water hybrid nanofluid flow in a trapezoidal cross-sectioned channel under turbulent regime (104<Re<105) for the first time. Understanding main source entropy generation along channel, also obtaining total variation comparing to single nanofluids (Al2O3/water Cu/water) base fluid is pursued objective. In other perform these aforementioned analyses, realistic model, which all formulas are derived, developed thermodynamic concepts such as efficiency destruction non-circular discussed Results from both have been compared volumetric concentrations 1.0% 2.0%. As result, it obtained that 2.0% volume concentration offers best convective heat transfer performance with 34% enhancement exergetic performance. Furthermore, has lowest value.
