“…Table 2 describes the conformation of the present outcomes by comparing with the existing literature for certain limited special cases. 6,10,15,18,19 The comparison shows an intelligent agreement for all Pr and Ec values, confirming the validity of current results. For numerical outcomes, we considered values of dimensionless parameters as ϕ 1 = 0.1, ϕ 2 = 0.1, Sq = 0.5, De = 0.5, δ = 0.1, Rd = 0.2, Pr = 6.2, θ w = 2, and Ec = 0.1.…”

“…Gul et al 9 described how mixed convection effects the generation of entropy in the Poiselle flow of Jeffry nanofluid using perturbation technique. The effects of thermal radiation, viscosity dissipation, and entropy creation on Maxwell nanofluid through a squeezing channel were studied recently by Shit and Mukherjee 10 using the differential transformation approach. They came to the conclusion that when Deborah increases, the heat transmission rate decreases.…”

The hydrothermal performance of a hybrid nanofluid made of graphene, gold/polydimethylsiloxane between two squeezing plates is discussed in this study. In the investigation of thermal transport of the flow, both linear and nonlinear thermal radiation's effects are taken into account. Bejan numbers are used to determine the system's energy efficiency. Viscous and thermal radiation effects on Maxwell hybrid nanofluid flow in a squeezing channel are incorporated to explore the outcomes. By applying similarity transformations, the set of ordinary differential equations in this case is transformed into the governing equations. With the use of the Runge–Kutta–Fehlberg technique converted system is solved numerically. Skin friction and heat transfer rates under the influence of certain oriented parameters are numerically analysed and presented in tabular form. The impacts of different factors on the temperature and velocity profiles are illustrated graphically and briefly described. Important findings include that the Bejan number raises as the radiation parameter Rd rises, but that it falls with respect to the Eckert number effect. Additionally, the skin friction values and Nusselt number in the hybrid nanofluid case are larger than in the nanofluid case. Furthermore, it has been found that the Deborah number-described stress relaxation phenomenon causes the flow field and thermal energy transfer to be less efficient when fluids are moving. There is surprisingly little research on the hybrid fluid integrated into their issues.

This study investigates the unsteady Maxwell nanofluid flow past a stretching surface, embedded in a porous medium, in the presence of magnetic field and thermal radiation effects. Polydimethylsiloxane (PDMS) is considered as a Maxwell base fluid and graphene is taken as nanoparticle to form the nanofluid. It is a well‐reported fact in the literature (Boland et al. Science, 354(2016)1257) that viscous graphene polymers can be used to make sensitive electromechanical sensors, thereby setting the direction and incentive for the study of graphene–PDMS nanofluid. In this paper, we have implemented the Navier's slip boundary condition at the nanofluid‐surface interface. Entropy analysis for the energy efficiency of the system in terms of the Bejan number is carried out extensively. By employing suitable similarity transformations, the set of partial differential equations has been transformed into a set of ordinary differential equations. The transformed equations are solved by the homotopy analysis method (HAM). The nanofluid velocity, temperature, skin‐friction coefficient, and heat transfer rate are analyzed in this paper under several regulatory physical parameters. The findings show that the rise in time relaxation parameter has adverse effects on nanofluid velocity but enhances the entropy generation in the system. The heat transfer rate decreases with an enhancement of the Deborah number but increases with a rise in the nanoparticle volume fraction. The Bejan number shows increasing trend with an enhancement of unsteady parameter, nanoparticle volume fraction, and porous permeability parameter. This study bears the potential application in powder technology, plastic extrusion process, as well as in bio‐engineering.

“…Thermal radiation phenomena in blood flow and heat transfer have numerous applications in biomedical engineering and numerous medical handling methods, primarily in thermal therapeutic dealings, industrial and space technological products such as furnace design, nuclear reactor safety, fire spreads, solar fans, fluidized bed heat reactors, turbid water bodies, photochemical reactors, and so on. [43][44][45] Linear thermal radiation is only effective when the temperature gradient is very low. However, it is ineffective when the temperature gradient is extremely variable.…”

In the present study, we examine the influence of entropy generation on Maxwell hybrid nanofluid over a cylinder in the presence of non-linear thermal radiation and Cattaneo-Christov heat flux. In this model, we considered [Formula: see text] and [Formula: see text] are the nanoparticles which are suspended in the base fluid blood. The basic PDE’s (Partial differential equations) are transformed into ODE’s (Ordinary differential equations) by ensuring the suitable self-similarity transformations. ODEs are resolved using a Runge–Kutta 4th-order along with shooting procedure. Numerical method ( NM) and Homotopy perturbation method ( HPM) solutions for the nonlinear system are obtained so that they compared to each other for the case of cylinder. The HPM is developed for comparison purposes, and more accurate and reliable outcomes are illustrated through graphs. Moreover, the obtained results are compared with the existing literature and are found to be an excellent agreement. It is found that the fluid velocity reduces for the higher values of magnetic parameter. Higher values of the heat generation parameter improve the temperature profiles. Nusselt number decreases when developing Darcy–Forchheimer number and temperature time relaxation parameter. This type of flow problems may be utilized to improve the blood flow in the blood vessel has attracted the attention of physicians and biomedical researchers as it specializes in various treatments such as drug targeting, cell tissue engineering, cancer, hyperthermia and hypothermia.
