Effectiveness of heat and mass transfer on mixed convective peristaltic motion of nanofluid with irreversibility rate

Entropy generation is one of the key features in the analysis as it exhibits irreversibility of the system. Therefore, present study investigates entropy generation rate in a mixed convective peristaltic motion of a reactive nanofluid through an asymmetrical divergent channel with heat and mass transfer characteristics. Endorsed nanofluid model holds thermophoresis and Brownian diffusions. Mathematical modeling is configured under the effects of mixed convection, heat generation/absorption and viscous dissipation. Chemical reaction is also introduced for the description of mass transportation. Resulting system of differential equations is numerically tackled by employing the Shooting method. Findings reveal that entropy generation rises by improving Brownian motion and thermophoresis parameters. Temperature of nanofluid decreases by rising buoyancy forces caused by concentration gradient. Concentration profile increases by increasing chemical reaction parameter. Velocity increases by enhancing Brownian motion parameter.
