Dynamical dissipative and radiative flow of comparative an irreversibility analysis of micropolar and hybrid nanofluid over a Joule heating inclined channel

www.nature.com/scientificreports OPEN Dynamical dissipative and radiative flow of comparative an irreversibility analysis of micropolar and hybrid nanofluid over a Joule heating inclined channel S. Suresh Kumar Raju This report scrutinized the influence of radiation and Ohmic heating on the dissipative flow of micropolar and hybrid nanofluid within an inclined length 2h channel under convective boundary conditions. Primary flow equations are renewed as the system of NODEs with the assistance of proper similarity conversions. In two circumstances, hybrid fluid flow and micropolar fluid flow, a blend of shooting and Runge–Kutta 4th order strategy, is used to achieve the desired results. The critical consequences of the current study are Larger pressure gradient minimizes the fluid velocity, and a more significant inertia parameter minimizes the rotation profile in the case of Newtonian fluid flow but facilitates the same in the case of hybrid nanofluid flow. It is perceived that the escalation in Brinkmann number causes the amelioration in the fluid temperature, and the radiation parameter mitigates the same. Furthermore, it is discovered that the Grashoff number enhances the Bejan number at the centre of the channel but lessens the same at other areas. Finally, validation is executed to compare the current outcomes with the former results and perceive a good agreement. Hydrous or unsteady globes might also be electrically conductive and capable of withstanding core fluxes commencing electromagnetic stimulation. Instances of this occurrence are occasionally named induction boiler or Joule heating. These constituents of ohmic heating are offered in various manufacturing, industrial and cosmological sceneries. By viewing this, Makinde and G bolagade1 investigated entropy generation in a laminar viscous fluid flow via an inclined passage. They discovered that fluid friction’s irreversibility dominated heat transfer’s irreversibility on the channel centerline. Guimaraes and M enon2 conducted a heat transmission investigation of mixed convective fluid within an inclined channel (rectangular) with the help of the finite element technique. Dar and Elangovan3 inspected the impact of a magnetic field on the peristaltic flow through an inclined channel (asymmetric) and acknowledged that the magnetic field lessens the fluid velocity. Shahri and S arhaddi4 emphasized that the main reason for entropy generation is the heat conduction of nanofluid (water–Cu) in their examination of MHD fluid flow within an inclined channel. By assuming a low Reynolds number and considering an inclined channel, Javed et al.5 scrutinized the peristaltic flow with the Hartmann number. They concluded that the Hartmann number escalates the trapped bolus size. Hayat et al.6 analyzed the peristaltic transport of the pseudoplastic fluid flow in the same parameter with heat source and Joule heating. Reynolds number ameliorates the fluid temperature is one of the findings of this study. Tlau and Ontela7 considered convective conditions and elucidated the mixed convective flow of H2 O + Cu a tended channel occupied with a permeable medium. They observed the enhancement in the fluid velocity with a greater inclination angle. With the assumption of the same geometry, Adesanya et al.8 and Singh et al.9 proposed a model for different fluid flows to discuss the irreversibility analysis. They discovered that there is a reduction in the entropy generation rate with a couple of stress parameters. Sabu et al.10 used a correlation coefficient to examine the features of engineering parameters in an unsteady MHD nanofluid flow with the heat source. They detected that the Soret number is negatively affiliated Department of Mathematics and Statistics, College of Science, King Faisal University, Al‑Ahsa 31982, Saudi Arabia. email: Scientific Reports | (2023) 13:5356 | https://doi.org/10.1038/s41598-023-31920-1 1 Vol.:(0123456789) www.nature.com/scientificreports/ with the Sherwood number. Several researchers11–14 recently examined different fluid flows (including hybrid nanofluid) via similar geometry and highlighted that inclined geometry control the flow and heat transfer process. Improvement in the transfer of heat across fluid movement has made authorities in thermal manufacturing encirclement the efficiency of a combination of solid nanoparticles called a Hybrid nanofluid. The previously revealed improvement is based on the nature of the base fluid and nanoparticles. Solid particle concentration and thermal properties on the proportion of mass to density and viscidness are precisely the physical possessions. Nevertheless, thermal conductivity and specific heat capacity at different intensities of concentration of nano-solid particles, nanoparticles’ size, and temperature are some of the thermal possessions. Considering this, Gholinia et al.15 illustrated the MHD flow of a nanofluid (Ethylene glycol + Silver + Copper) by a circular cylinder with injection/suction. They concluded that the silver nanoparticles are better than copper when a higher temperature is required. Nadeem et al.16 numerically investigated a nanofluid (Water + SWCNT) flow by a curled sheet with a magnetic field. They observed that the volume fraction of nanoparticles ameliorates the fluid temperature. Sowmya et al.17 assumed longitudinal fin as geometry and examined the convective flow of a nanofluid (alloys of titanium and aluminium) with radiation. Dogonchi et al.18 inspected the radiative flow of Cu + H2 O fluid with a heat source and two reactions (heterogeneous–homogeneous) by a flat plate. They found a positive association between the Nusselt number and the magnetic field parameter. Newly, Anuar et al.19 and Waqas et al.20 assumed distinct geometries and scrutinized different water-based nanofluid flows under various conditions. Jamshed and A ziz21 did an irreversibility analysis on the Casson HNF (TiO2 − CuO/EG) flow by an elongating surface with the CCHF model. They found that the Brinkman number escalates the entropy generation. Salman et al.22 considered FFS and BFS and reviewed various hybrid nanofluid flows. They opined that HNFs are the best alternates compared to mono NFs when better thermal features are required. Abbas et al.23 assumed a thin needle and inspected the forced convective flow of an HNF (Water + SWCNT + MWCNT) with variable thermal conductivity. Anuar et al.24 and Waini et al.25 delivered a stability study for the radiative HNF (Cu − Al2 O3 /Water) flow by a revolving shrinking/elongating sheet. Based on that, they categorized the solutions as stable and unstable. Recently, various researchers26–37 considered different geometries as well as the combination of solid nanoparticles and generated intermediate kinds of conductivity properties. This helps us to highlight the intermediatory processes. Once the careful insight of the earlier stated inscription, we propose to discourse the importance of the radiation and (...truncated)
