Irregular heat source and non-linear convective Heat & mass transfer in Hybrid nano material passed through concentric cylinder

Abstract: An analysis of convective heat and mass transfer of nanofluids flow that are connected to an annulus-shaped, two concentric cylindrical regions are studied. The hybrid nanoparticles in Cu-Au and water-based hybrid nano liquids are considered, the salient features of convection in an inclined porous annulus are analysed. The conservation laws are in a non-linear model for the geometry considered. Using the appropriate analogues transformations, the resultant equations are employed RK-4th order method with shooting technique to obtain closed form solutions for transverse velocity, temperature, and concentration. The consequences of key parameters on the non-dimensional velocity, temperature, concentration, skin friction coefficient are presented through surface plots. The second order resistance and mixed convection mechanisms favours the flow structure. The velocity, temperature and concentration fields are greater for platelet-shaped nanoparticles, when compared to cylinder, bricks, and spherical-shaped nanoparticles. Applications of cylinders in nuclear waste disposal, energy extraction in catalytic beds. The observations of the present investigation are in good agreement with the flow structure of various physical parameters with the existing ones.
