Double Diffusion of Blood-Gold Carreau Nanofluid Using Partial Slip

Abstract

The investigation of double diffusive convection for the blood-gold Carreau nanofluid over an upper horizontal surface of a paraboloid of revolution (uhspr) with partial slip is the subject of this paper. It is assumed that the Carreau nanofluid corresponding to an infinite shear-rate is zero. The regulating PDE’s are converted into ODE’s by using the appropriate transformations. The reduced system of ODE’s is solved by using the RK-4th order method with the help of collocation formula bvp4c defined in Matlab software. The numerical computations for emerging parameters on the velocity, temperature, concentration, partial slip, etc. have been investigated for both shear-thinning and shear-thickening. The outcome of the study reveals that the velocity increases and temperature decreases with the rise in buoyancy parameters in both respects of small value of partial slip λ = 0.1 and large magnitude of partial slip λ = 2 while dual effects on the concentration gradient is observed at the boundary and free stream. Furthermore, these findings are in perfect agreement with previously published work on special cases.
