“…Eid et al 40 investigated and incorporated homogeneous and heterogeneous catalysis on electromagnetic radiational Prandtl fluid flow with the theory of the Darcy-Forchheimer substance scheme. Sahu et al 41 examined the thermal implications with SWCNT/ MWCNT suspensions and the Darcy-Forchheimer flow behavior as a result of the rotating disk's shrinkage. In this regard, many researchers have studied the Darcy Forchheimer fluid flow for different industrial and engineering fields for heat transfer applications.…”

The potential of hybrid nanofluid (HNF) to maximize heat transportation has captured the attention of many researchers, inspiring them to further investigate the performance of the common base fluid. Conventional flow in Cu-Al2O3/H2O hybrid nanofluid (HNF) toward a high permeability horizontal flat plate incorporated in Darcy porous medium has been explored in this research to determine how Cu-Al2O3/H2O hybrid fluid will respond thermodynamically when physical factors like suction/injection and slip boundary conditions are present. In addition, the effects of radiation, dissipations, energy engagement, and inclined magnetized field associated with the fluid flow were studied. The governing system is transformed by similarity transformations to a solvable ordinary differential equation by employing HAM (Homotopy Analysis Method) scheme. The main results show that Cu-Al2O3/H2O has high thermal conductivity compared to Cu/H2O. As a result, hybrid fluids are essential for the development of thermal phenomena.

“…Rasool et al (2022) described the Darcian–Forchheimer flow based on CNT nanoliquid flow due to a cavity along the impact of entropy generation and have deduced that at the center of the conduit, the fluid velocity has augmented with a larger Darcy number. Sahu et al (2022). explained thermal characteristics for the Darcy–Forchheimer flow of fluid by suspending MWCNTs/SWCNTs on a rotary shrinking surface and explored that the temperature characteristics of the system have been augmented by reducing the production of entropy with higher values of porosity number.…”

Purpose The modern day has seen an increase in the prevalence of the improvement of high-performance thermal systems for the enhancement of heat transmission. Numerous studies and research projects have been carried out to acquire an understanding of heat transport performance for their functional application to heat conveyance augmentation. The idea of this study is to inspect the entropy production in Darcy-Forchheimer Ree-Eyring nanofluid containing bioconvection flow toward a stretching surface is the topic of discussion in this paper. It is also important to take into account the influence of gravitational forces, double stratification, heat source–sink and thermal radiation. In light of the second rule of thermodynamics, a model of the generation of total entropy is presented. Design/methodology/approach Incorporating boundary layer assumptions allows one to derive the governing system of partial differential equations. The dimensional flow model is transformed into a non-dimensional representation by applying the appropriate transformations. To deal with dimensionless flow expressions, the built-in shooting method and the BVP4c code in the Matlab software are used. Graphical analysis is performed on the data to investigate the variation in velocity, temperature, concentration, motile microorganisms, Bejan number and entropy production concerning the involved parameters. Findings The authors have analytically assessed the impact of Darcy Forchheimer's flow of nanofluid due to a spinning disc with slip conditions and microorganisms. The modeled equations are reset into the non-dimensional form of ordinary differential equations. Which are further solved through the BVP4c approach. The results are presented in the form of tables and figures for velocity, mass, energy and motile microbe profiles. The key conclusions are: The rate of skin friction incessantly reduces with the variation of the Weissenberg number, porosity parameter and Forchheimer number. The rising values of the Prandtl number reduce the energy transmission rate while accelerating the mass transfer rate. Similarly, the effect of Nb (Brownian motion) enhances the energy and mass transfer rates. The rate of augments with the flourishing values of bioconvection Lewis and Peclet number. The factor of concentration of microorganisms is reported to have a diminishing effect on the profile. The velocity, energy and entropy generation enhance with the rising values of the Weissenberg number. Originality/value According to the findings of the study, a slip flow of Ree-Eyring nanofluid was observed in the presence of entropy production and heat sources/sinks. There are features when the implementations of Darcy–Forchheimer come into play. In addition to that, double stratification with chemical reaction characteristics is presented as a new feature. The flow was caused by the stretching sheet. It has been brought to people's attention that although there are some investigations accessible on the flow of Ree-Eyring nanofluid with double stratification, they are not presented. This research draws attention to a previously unexplored topic and demonstrates a successful attempt to construct a model with distinctive characteristics.

This research work describes and investigates Williamson nanofluid flow over an exponentially stretching permeable vertical plate with temperature-dependent thermal conductivity and viscosity. The governing non-linear partial differential equations (PDEs) are metamorphosed into coupled non-linear ordinary differential equations (ODEs) by using similarity transformation. The succeeding equations were numerically solved using MATLAB function bvp4c for various values of parameters. For velocity, temperature, concentration, the skin friction coefficient, and the local Nusselt number, data are presented in the form of graphs and tables. It is noted that for increasing values of magnetic parameter , Williamson parameter and viscosity parameter , the boundary layer thickness of the velocity profile decreases, while it increases for the temperature profile. The findings of the present work are validated through the published results.
