Study of Al2O3/copper–water nanoparticle shape, slip effects, and heat transfer on steady physiological delivery of MHD hybrid nanofluid

The paper contains the analytical investigation of magnetohydrodynamic (MHD) flow of (Copper Al2O3)/ water hybrid nanofluid with unstable peristaltic motion. Three different geometries (such as bricks, cylinder and platelets) along with velocity and thermal slip conditions are studied in detail in order to reach the precise solution. Flow geometry of a non-uniform tube of finite length, experimental values of base fluid and considered nanoparticles are taken into account to examine the theoretical investigation of formulated equations. Dimensionless control equations which are subject to physically realistic boundary conditions are closely studied to obtain precise results. The shape effects of nanoparticles on velocity, temperature distribution and heat transfer on the length of the non-uniform tube with variation of the various flow parameters are discussed in a graphical description to understand the theoretical aspects in order to validate the medical analysis. The observations from the analysis states that (Copper Al2O3)/ water carry maximum velocity for smaller values of slip parameters. Temperature distribution for heat absorption parameter are more significant as fluid flow accelerates when large values are chosen. Large values of thermal slip parameter yield enhancement in pressure gradient and cu-water nanofluid has higher impact than hybrid nanofluid. Platelets shape nanoparticles of hybrid nanofluid has more significant effect on pressure gradient as compare to cylinder and bricks shape nanoparticles of Cu-water nanofluid. An intrinsic property of peristaltic transport i.e trapping is also discussed. The trapped bolus decreases for platelets and cylinder shapes nanoparticles, whereas, the size of the trapped bolus increases for bricks shapes nanoparticles. This model is applicable to a drug delivery system and to design the micro peristaltic pump for transporting nanofluids.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
