In the present study, our aim is to present a novel model for the flow of hybrid nanofluids in oblique channels. Copper and aluminum oxide have been used to obtain a novel hybrid nanofluid. The equations that govern the flow of hybrid nanofluids have been transformed to a set of nonlinear equations with the implementation of self-similar variables. The resulting system is treated numerically by using coupled shooting and Runge-Kutta (R-K) scheme. The behavior of velocity and temperature is examined by altering the flow parameters. The cases for narrowing (convergent) and opening (divergent) channels are discussed, and the influence of various parameters on Nusselt number is also presented. To indicate the reliability of the study, a comparison is made that confirms the accuracy of the study presented.

Thermal transport investigation in colloidal suspensions is taking a significant research direction. The applications of these fluids are found in various industries, engineering, aerodynamics, mechanical engineering and medical sciences etc. A huge amount of thermal transport is essential in the operation of various industrial production processes. It is a fact that conventional liquids have lower thermal transport characteristics as compared to colloidal suspensions. The colloidal suspensions have high thermal performance due to the thermophysical attributes of the nanoparticles and the host liquid. Therefore, researchers focused on the analysis of the heat transport in nanofluids under diverse circumstances. As such, the colloidal analysis of H2O composed by gamma Al2O3 and Al2O3 is conducted over an elastic cylinder. The governing flow models of gamma Al2O3/H2O and Al2O3/H2O is reduced in the dimensionless form by adopting the described similarity transforms. The colloidal models are handled by implementing the suitable numerical technique and provided the results for the velocity, temperature and local thermal performance rate against the multiple flow parameters. From the presented results, it is shown that the velocity of Al(2)O3-H2O increases promptly against a high Reynolds number and it decreases for high-volume fraction. The significant contribution of the volumetric fraction is examined for thermal enhancement of nanofluids. The temperature of Al2O3-H2O and gamma Al2O3-H-2O significantly increases against a higher phi. Most importantly, the analysis shows that gamma Al2O3-H2O has a high local thermal performance rate compared to Al2O3-H2O. Therefore, it is concluded that gamma Al2O3-H2O is a better heat transfer fluid and is suitable for industrial and technological uses.

Second Law Analysis of Magneto Radiative GO-MoS2/H2O-(CH2OH)2 Hybrid Nanofluid
(Tech Science Press, 2021) Adnan; Baleanu, Dumitru; Khan, Umar; Ahmed, Naveed; Mohyud-Din, Syed Tauseef; Baleanu, Dumitru; Nisar, Kottakkaran Sooppy; Khan, Ilyas; 56389; Matematik
Entropy Generation Optimization (EGO) attained huge interest of scientists and researchers due to its numerous applications comprised in mechanical engineering, air conditioners, heat engines, thermal machines, heat exchange, refrigerators, heat pumps and substance mixing etc. Therefore, the study of radiative hybrid nanofluid (GO-MoS2/C2H6O2-H2O) and the conventional nanofluid (MoS2/C2H6O2-H2O) is conducted in the presence of Lorentz forces. The flow configuration is modeled between the parallel rotating plates in which the lower plate is permeable. The models which govern the flow in rotating system are solved numerically over the domain of interest and furnished the results for the temperature, entropy generation and thermophysical characteristics of the hybrid as well as conventional nanofluids, respectively. It is examined that the thermal profile intensifies against stronger thermal radiations and magnetic field. The surface of the plate is heated due to the imposed thermal radiations and magnetic field which cause the increment in the temperature. It is also observed that the temperature declines against more rotating plates. Further, the entropy production increases for more dissipative effects and declines against more magnetized fluid. Thermal conductivities of the hybrid nanofluid enhances promptly in comparison with regular liquid therefore, under consideration hybrid nanofluid is reliable for the heat transfer. Moreover, dominating thermal transport is perceived for the hybrid nanofluid which showed that hybrid suspension GO-MoS2/C2H6O2-H2O is better for industrial, engineering and technological uses.
