SISKO NANOFLUID FLOW OVER A VERTICAL STRETCHING SHEET IN A POROUS MEDIUM: A NUMERICAL STUDY
Present work focuses on the numerical simulation of Sisko
nanofluid flow and heat transfer in a porous medium along with
a vertical linear stretching sheet. Buongiorno model for nanofluids is considered to study the effect of Brownian diffusion and thermophoresis on heat transfer of Sisko nanofluid. The governing equations are presented in the dimensionless form with the help of suitable similarity transformation. The transformed nonlinear coupled differential equations are solved numerically by Finite difference method in MATLAB software. The behavior of velocity, temperature and nanoparticle volume fraction under different physical parameters such as buoyancy parameter, porosity parameter, etc. are presented graphically. Further, the influence of this physical parameter on the heat transfer rate is also discussed. It has been observed from the obtained results that the impact of buoyancy parameter is to enhance the velocity and nanoparticle volume fraction while reduce the temperature
whereas porosity parameter reduces the velocity and enhances
the nanoparticle volume fraction and temperature of the fluid.
