“…Further, the more recent attractive investigations of various models with CCTM and their effectiveness under the different physical constraint's levels described in the literary works. [7][8][9][10][11][12] Recently, researchers turned their idea towards hybrid types of nanofluids to achieve enhanced heat transfer for realistic applications. Thus, Animasaun et al 13 and Bhatti et al 14 reported the studies for ternary and hybrid nanofluids through horizontal and vertical channel flow situations.…”

Applications: The dynamics of superior heat transport fluids are of much interest and dominant over traditional fluids. Applications of such fluids can be found in advanced medical sciences, to maintain the building temperature, environmental sciences, chemical engineering, food engineering, and other applied research areas where enhanced heat transfer is required. Aim and Research Methodology: The major aim of this research is to report the thermal performance of the Glycerin-titania nanofluid using a thermal conductivity model comprising the effects of nanoparticles aggregation, and CCTF over a permeable slanted surface. The enhanced heat transport model was then analyzed numerically via RK scheme and furnished the outcomes with graphical aid under the variations of physical parameters. Core Findings: It is examined that the addition of CCTF (A1) in the model potentially contributes to thermal performance of aggregated nanofluid. The temperature [Formula: see text] enhances for injecting fluid from the surface and reduces due to strong suction. Further, the fluid particles attained maximum velocity for [Formula: see text] at the surface and it shows asymptotic behavior far from the working domain.

This paper presents the nonlinear frequency behavior of cracked functionally graded porous beams subjected to various boundary conditions using Reddy shear deformation theory and Green’s tensor together with the Von Karman geometric nonlinearity. The material properties of the beam vary exponentially in thickness direction. A generalized differential quadrature method (GDQM) in conjunction with a direct numerical iteration method is developed to solve the system of equations derived by means of Hamilton’s principle. Demonstrating the convergence of this method, the verification is performed by using extracted results from a previous study based on the Euler and Timoshenko beam theory. The results for extensive studies are provided to understand the influences of the different gradient indexes, vibration amplitude ratios, porosity indexes, shear and elastic foundation parameters, and boundary conditions on the nonlinear frequency behavior. The location of crack plays the significant role on the nonlinear frequency ratios. The frequency ratios hit the minimum when the crack is located in mid-span of the beam. In this regard, the effect of shear stiffness of foundation is much more than that of Winkler one in the increasing mid-span value of nonlinear frequency ratio. It is also shown that the crack location results in decline of frequency ratios in the mid-span of beam specially for the cracks located closer to surface, the deeper ones lead to get nonlinear frequency ratios rise much more due to the fact that the deeper the crack is, the weaker the crack section becomes. The results of this paper and the effects of these parameters can be used in the optimal design of functionally graded beams and in crack prediction, detection, and monitoring techniques.

As the primary energy source derived from the sun, solar energy is widely utilized in various technologies, including photovoltaic cells as well as the solar types of energy plates, street lights, and water pumping. This era is about studying solar radiations and a way to active enhancements in solar power pump (SWP) efficacy with the use of solar radiations and nanotechnology. Communication is structured to examine the capability of SWP in terms of transfer of heat using a hybrid nanofluid passing through a parabolic trough surface collector (PTSC) placed inside the pipeline of SWP. Solar radiation has been considered a heat source. The performance in terms of heat transfer of the SWP is scrutinized for various effects like porous media, viscous dissipation, radiative heat flux, and Cattaneo–Christov heat flux (C–CHF). Entropy generation analysis is also conducted for Prandtl – Eyring fluid (P-EF). The simulated momentum and energy equations were solved using the Keller box technique, which is a well-known numerical approach. For this work, Prandtl – Eyring hybrid nanofluid (P-EHNF) has been considered, consisting of double diverse kinds of nanotubes (NT), including single-walled carbon nanotubes (SWCNT) and multi-walled carbon nanotubes (MWCNT) in the rich, viscous fluid of kind Sodium Alginate (SA). The impact of various parameters on velocity, temperature fields, shear stress, coefficient of drag force, and Nusselt number are investigated and demonstrated in graphs and tables. The SWP experience an enhancement in the transfer of heat for amplification of the parameters of thermal radiative flow as well as viscous dissipation. In comparison with conventional nanofluid, hybrid nanofluid performs better in heat transmission. The thermal efficacy of MWCNT/SWCNT-SA over SWCNT-SA got down to a minimal level of 39.9% and peaked at 42.2%.
