Entropy generation in nanofluid flows is a critical parameter that influences the performance, efficiency, and sustainability of thermal systems. Understanding optimizing entropy creation can lead to noteworthy advancements numerous engineering applications, from renewable energy systems industrial processes biomedical equipments. The purpose this article examine produced bioconvection flow Eyring-Powell nanomaterial with gyrotactic microorganisms. mathematical equations representing are modeled considering towards porous surface cylinder. Together effects governing parameters, mass heat transfer components problem discussed. different natures used new way. Overall, designed regard second law thermodynamics. Activation energy, chemical reaction, radiation, internal friction force accounted for development model. Coupled non-linear dimensional have been altered into ordinary differential (ODEs) then treated using MATLAB Finite Difference Method (FDM). Consequence diverse sundry parameters on production, field, concentration profile, Bejan quantity, motile density microorganisms deliberated via plots. Through tables, quantities analyzed. According findings, velocity profile rises as curvature fluid rise, while it falls when magnetic enhanced. Additionally, noted variable enhances, rate skin coefficient decays.

Abstract Previous works that investigated the characteristics of heat transfer and fluid flow in channels with corrugated walls have been extensively reviewed this study. In accordance fast increase power consumption requirements, many researchers a new approach for cooling techniques can enhance performance devices without consuming more power. To improve efficiency energy systems, investigators engineers implement promising such as surface optimization additives passive methods to augment rates transfer. Researchers different corrugation profiles along various working fluids well external further exchange process thermal systems. The aim article is give clear preview effects parameters wave parameters, Reynolds number, type fluid, pulsating condition on average local Nusselt pressure drop, factors, irreversibility. main findings are listed tables depicted figures, matter helps choose suitable channel shape their applications.

The physical properties of working fluids—in terms the Prandtl number—play a crucial role in determining their thermal performance internal flow, especially viscosity. This study first considers thermo-hydraulic and entropy generation sinusoidal corrugated channel two configurations: symmetrical (raccoon) asymmetrical (serpentine). Results are presented for different ranges operating parameters, such as 100≤Re≤700 0.72≤Pr≤90, geometrical parameters wave amplitude-to-wavelength ratio 0.2≤α≤0.6. In addition, results channels were compared with each other's straight channel. Control transport equations solved using finite element methods. It was found that flow inside wavy generated re-circulatory reigns, size affected by well Reynolds number. Also, employing high values Pr extremely enhanced heat transfer rate (HTR) over all α both raccoon serpentine channels. indicated have higher HTR factor to Finally, dominated viscous its decrease number focused on enhancement due importance many industrial applications where dissipation is critical work, including exchangers sinks. Thus, current numerical simulation primarily suggests utilizing one, nearly same total generation.
