“…After that, Wang [6] presented the analytic solutions for the thin film flow and heat transfer problem over an unsteady accelerating sheet. The strong contributions of [3][4][5][6] are the impetus for the thin film flow and heat transfer research under the following effects: thermocapilarity [7,8], general surface temperature [9,10], thermal radiation [11], magnetohydrodynamics (MHD) [12], viscous dissipation [13], slip effects [14,15].…”

Melting heat transfer has a vital role in forming energy storage devices such as flexible thin film supercapacitors. This idea should be welcomed in the thin film theoretical models to sustain technological advancement, which could later benefit humankind. Hence, the present work endeavors to incorporate the melting heat transfer effect on the Carreau thin hybrid nanofluid film flow over an unsteady accelerating sheet. The mathematical model that obeyed the boundary layer theory has been transformed into a solvable form via an apt similarity transformation. Furthermore, the collocation method, communicated through the MATLAB built-in bvp4c function, solved the model numerically. Non-uniqueness solutions have been identified, and solutions with negative film thickness are unreliable. The melting heat transfer effect lowers the heat transfer rate without affecting the liquid film thickness, while the Carreau hybrid nanofluid contributes more entropy than the Carreau nanofluid in the flow regime.

“…Singh et al 46 presented the influence of entropy generation on fluid flow through an inclined channel with vortex viscosity and thermal conductivity and the results showed that entropy generation enhanced with temperature and viscous conductivity parameters. In a study by Yusef et al 47 on irreversibility in a micropolar gravity‐driven fluid flowing in an oblique permeable substratum with slip restrictions, the results revealed that enhancement in the value of microrotation decreases the velocity gradient.…”

The present work explores the consequence of the flow of micropolar fluid in an inclined microchannel when exposed to linear radiation in presence of a magnetic field. The microchannel is embedded with a porous medium and the Darcy-Forchheimer model is implemented. The walls of the microchannel facilitate the simultaneous suction and injection of the micropolar fluid. A multiple slip regime and temperature jump conditions were assumed at the boundaries. The equations are modeled and nondimensionalized using nondimensional entities and further solved with the aid of the Runge-Kutta-Fehlberg method. Entropy generated in the medium and ratio of irreversibilities is also computed. Results so obtained deliberate that enhancement in Darcy number has caused an increment in entropy generation rate whereas the opposite nature is attained for the Bejan number. Magnifying the radiation parameter has resulted in diminishing the profile of entropy generation rate and Bejan number.

“…Chand et al [21] analyzed the rule of linear stability hypothesis in their theoretical examination of thermal convection in a horizontal layer of micropolar nanofluid. Yusuf et al [22] give an investigation of the irreversibility of a micropolar fluid film moving down an inclined porous substrate with slip effect. Squeezing flow of a Casson-micropolar nanofluid with injection/suction and slip effects was studied by Ramesh et al [23].…”

The work's goal is to learn more about how a magnetic field, Brownian motion, and thermophoresis diffusion influence convective heat transfer in a micropolar-nanofluid flow's laminar boundary layer. Near a vertically moving, permeable plate, the complex fluid is subjected to MHD. The MATLAB application bvp4c was utilized to simplify the governing nonlinear and coupled equations for the micropolar-nanofluid, leading to the solution of the ensuing ordinary differential equations (ODEs). Graphs have been used to analyze the effect of different relevant active factors on the flow field and temperature. The results demonstrate that the micro-rotation of the nanoparticles taken into account and in suspension becomes significant for the complex fluid in the presence of the magnetic field. Analysis of the generation entropy shows that the surface is a significant source of irreversibility. There is no discernible effect of micropolarity on the relationship between Brownian and thermophoresis numbers and entropy generation.
