“…In the ever-evolving landscape of research, recent trends underscore the efficacy of incorporating special fluids, including nanofluids, hybrid nanofluids and non-Newtonian fluids, when exploring natural convection within porous enclosures (Zahor et al, 2023;Alsabery et al, 2023;Ramesh et al, 2023;Biswas et al, 2022a). Notably, nanofluids and hybrid nanofluids emerge as promising alternatives to conventional fluids, exhibiting the potential to enhance convective heat and fluid flow phenomena within porous media (Kaswan et al, 2023;Agrawal and Kaswan, 2022). This enhancement is a result of the enriched thermophysical properties offered by these special fluids.…”

Purpose This study aims to analyze the impact of fractional derivatives on heat transfer and entropy generation during transient free convection inside various complex porous enclosures, such as triangle, L-shape and square-containing wavy surfaces. These porous enclosures are saturated with Cu-water nanofluid and subjected to the influence of a uniform magnetic field. Design/methodology/approach In the present study, Darcy’s model is used for the momentum transport equation in the porous matrix. Additionally, the Caputo time fractional derivative is introduced in the energy equation to assess the heat transfer phenomenon. Furthermore, the total entropy generation has been computed by combining the entropy generation due to fluid friction (Sff), heat transfer (Sht) and magnetic field (Smf). The complete mathematical model is further simulated using the penalty finite element method, and the Caputo time derivative term is approximated using the L1 scheme. The study is conducted for various ranges of the Rayleigh number (102≤Ra≤104), Hartmann number (0≤Ha≤20) and fractional order parameter (0<α<1) with respect to time. Findings It has been observed that the fractional order parameter α governs the characteristics of entropy generation and heat transfer within the selected range of parameters. The Bejan number associated with heat transfer (Beht), fluid friction (Beff) and magnetic field (Bemf) further demonstrate the dominance of flow irreversibilities. It becomes evident that the initial evolution state of streamlines, isotherms and local entropy varies according to the choice of α. Additionally, increasing Ra values from 102 to 104 shows that the heat transfer rate increases by 123.8% for a square wavy enclosure, 7.4% for a triangle enclosure and 69.6% for an L-shape enclosure. Moreover, an increase in the value of Ha leads to a reduction in heat transfer rates and entropy generation. In this case, Bemf→1 shows the dominance of the magnetic field irreversibility in the total entropy generation. Practical implications Recently, fractional-order models have been widely used to express numerous physical phenomena, such as anomalous diffusion and dispersion in complex viscoelastic porous media. These models offer a more accurate representation of physical reality that classical models fail to capture; this is why they find a broad range of applications in science and engineering. Originality/value The fractional derivative model is used to illustrate the flow pattern, heat transfer and entropy-generating characteristics under the influence of a magnetic field. Furthermore, to the best of the author’s knowledge, a fractional-derivative-based mathematical model for the entropy generation phenomenon in complex porous enclosures has not been previously developed or studied.

“…Agrawal and Kaswan (2023) studied heat transference behaviour on 3D squeeze flows. Likewise, Mousavisani et al (2020), Dogonchi et al (2020), Muhammad et al (2022) and Agrawal and Kaswan (2022) have considered the squeezing flow of fluids using analytical and numerical methods. The unsteady two-dimensional flow of magneto-hydrodynamic (MHD) viscous fluid amongst two analogous infinite plates in existence of electromagnetic arena using three different approaches was explored in Mustafa Inc and Akgul (2014), Dib et al (2015), Biswas et al (2021) and VenkataSubba Rao et al (2021).…”

Purpose This paper aims to explore the double diffusive magneto-hydrodynamic (MHD) squeezed flow of (Cu–water) nanofluid between two analogous plates filled with Darcy porous material in existence of chemical reaction and external magnetic field. Design/methodology/approach The governing nonlinear equations are transformed into ordinary differential equations by means of similarity transforms, and the coupled mass and heat transference equations are resolved analytically with the application of differential transform method (DTM). The effects of different relevant parameters on velocity, temperature and concentration, including the squeeze number, magnetic parameter, Biot number, Darcy number and chemical reaction parameter, are illustrated with figures. In addition, for various parameters, the local skin friction coefficient, local Nusselt number and local Sherwood number are computed and are graphically displayed. Findings It is observed that the squeeze number has a direct relationship with Sherwood number and an inverse relationship with skin friction as Biot number increases. With enhanced Biot numbers, the temperature value increases during both squeeze and non-squeeze moments, but the temperature values are higher for squeeze moments compared to the other case. Practical implications This research has potential applications in various large-scale enterprises that might benefit from increased productivity. Social implications The results are useful to thermal science community. Originality/value Unique and valuable insights are provided by studying the impact of chemical reaction on double diffusive MHD squeezing copper–water nanofluid flow between parallel plates filled with porous medium. In addition, this research has potential applications in various large-scale enterprises that might benefit from increased productivity.
