Advanced techniques are used to increase the efficiency of the energy assets and maximize the appliance efficiency of the main resources. In the recent study, the focus is paid to the solar collector to cover thermal radiation through optimization and enhance the performance of the solar panel. Hybrid nanofluids (HNs) consist of a base liquid (C3H8O2) glycol whereas copper (Cu), and aluminum oxide (Al2O3) are used as nanomaterials for formation (HNs). The flow of the stagnation point is considered in the presence of the Riga plate. The state of the solar thermal system is termed viva stagnation to control the additional heating through the flow variation in the collector loop. The inclusion of entropy generation and Bejan number formation is primarily conceived under the influence of physical parameters for energy optimization. The computational analysis was carried out utilizing the control volume finite element method (CVFEM), and Runge–Kutta 4 (RK-4) methods. The results are further validated through a machine learning neural networking procedure. The conclusions showed that the heat transfer rate is greatly upgraded with a variation of the nanoparticle's volume fraction. We expect this improvement to progress the stability of heat transfer in the solar power system.

Numerical analysis of Stefan blowing viscous fluid flowing above a stretching/shrinking disk

et al. 2023

An incompressible, axi‐symmetric and magnetized viscous fluid flowing above a rotating disk is addressed. The disk can be stretch/shrink with a constant rate along the radial direction. The variable fluid features such as the viscosity, thermal conductivity and mass diffusion are considered in the flow governing equations. Two different cases of mass blowing/suction are considered. In the first case, the injection/suction is considered through the disk surface. The second case of injection/suction is through the surface of the disk by concentration gradient named as the Stefan effect. Similarity variables are accomplished to transform the governing system of partial differential equations into an ordinary one's. The resulting flow model is solved by bvp4c solver. The obtained physical parameters are discussed on velocity, thermal and concentration fields. For the better understanding of the flow phenomenon, the three‐dimensional flow visualization and its two‐dimensional contours against the physical parameters are sketched. The Nusselt and Sherwood numbers and skin‐friction against distinct constraints are calculated. It is observed that the suction parameter decreased the radial velocity curves for the stretching disk, while the velocity profiles are modified along radial direction in case shrinking disk against the increased suction parameter. The skin‐friction coefficient is enhanced for mass injection/suction and Stefan blowing/suction cases against the higher magnetic parameter values. The enhancement in variable thermal conductivity causes a reduction in local‐Nusselt number as well as the Sherwood number.

To increase energy efficiency, the flow of fluids containing nanoparticles is crucial in industrial applications notably in nuclear reactors and nuclear system cooling. In light of this, this study examines the flow of a water‐based ternary hybrid nanofluid (graphene, single‐walled carbon nanotubes, and titanium dioxide) across a curved stretching sheet with suction. The non‐Fourier heat flux model is also considered in the modeling. The existing partial differential equations are converted into ordinary differential equations through the use of similarity variables. These ordinary differential equations are then numerically solved using the Runge–Kutta–Fehlberg fourth‐ and fifth‐order method along with a shooting approach. The collection of graphical findings for the key variables on the temperature and velocity profiles is investigated. Results reveal that the heat transport in ternary hybrid nanoliquid rises as the heat source/sink parameter rises. The Biot number influences the thermal profile positively, whereas the increasing curvature parameter values reduce heat transport. The curvature parameter has a positive impact on skin friction but the suction parameter has a negative impact on skin friction.
