【 摘 要 】

A theoretical study has been developed to explore peristaltically deformable curved channel flow of Sisko nanofluid with double-diffusive (thermal and concentration) convection. Such consideration supports the flow of fluid in biological vessels and arteries to transport the food contents, oxygen, waste products, heat, blood and several other nutrients to the body. The flow stream is regulated and restricted in laminar region by considering long wavelength (d≪λ→∞) and low Reynolds number (Re→0) in terms of velocity, temperature, concentration and nanoparticle volume fraction fields. Moreover the mathematical expressions are listed for mixed convection and viscous dissipation aspects. The outcomes of influential dynamic parameters are sketched as graphical flow patterns with focus towards double-diffusive convection. Computational technique NDSolve in Mathematica is employed. The results for classical Newtonian fluid are captured as a special case of this analysis. The upshots of this investigation can be supportive for an enhancement of gastrointestinal movements and pumping in several engineering devices.
