Comparative study of silver and copper water magneto nanoparticles with homogeneous-heterogeneous reactions in a tapered channel

The core purpose is here to analyze the peristaltic motion of an electrically conducting silver and copper water nanofluid in a tapered channel. Maxwell methodology is used to model the problem. Analysis is carried out in the presence of mixed convection, viscous dissipation and heat generation/absorption. Addition of homogeneous/heterogeneous effects has made this study more motivating. Galilean transformations are used to relate the two frames of reference. Simplified form of the governing equations is obtained via large wavelength and small Reynolds number approach. Results for stream function, velocity, temperature, heat transfer rate and homogeneous/heterogeneous reactants are studied and discussed precisely. Graphical results indicate that axial velocity of nanofluid enhances for larger Grashof number while decrease in the temperature of the nanoparticle is observed when porosity parameter is enhanced.
