摘要
Flows of the various conventional liquids diluted with different metals and their oxides are very important to overcome the engineering problems which required rapid heat transfer. In the light of this fact, flow of gamma Al2O3-H2O and gamma Al2O3-C2H6O2 rotating dissipative nano fluids. The applications of such nanofluids embedded in cooling, thermal system and electric engine generator etc. The problem is successfully transformed in self-similar form in Section Description of the problem for both gamma Al2O3-C2H6O2 and gamma Al2O3-C2H6O2. For this, suitable set of similarity transformations utilized. Then, solutions for the model are performed by means of Runge-Kutta numerical scheme. For said purpose, we used Software Mathematica 10.0. Behavior of the pertinent parameters on the velocity and thermal fields analyzed graphically. It is noticed that temperature of gamma Al2O3-C2H6O2 nanofluids dominant throughout the analysis. Influence of the volumetric fraction nanoparticles is almost similar for both gamma Al2O3-C2H6O2 and gamma Al2O3-C2H6O2. Numerical results for skin friction coefficient are calculated at upper and lower wall of the channel. For validity of current results, graphical comparison is also provided with already existing study. Present results are compared with previous ones and found an excellent agreement. Finally, core findings of the study ingrained in the last section. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
