Two-Phase Nanofluid Thermal Analysis over a Stretching Infinite Solar Plate Using Keller Box Method (KBM)

摘要

In the present study, two phase nanofluid flow in a three dimensional systemis modeled over a stretching infinite solar plate and the heat transfer analysis is performed for thisproblem. The governing equations are presented based on previous studies and the suitable solutionmethod is recommended due to infinite boundary condition in the problem. Keller Box Method(KBM) using the Maple 15.0 mathematical software is applied as the solution method forthe governing equation of the problem. The effect of some parameters existed in the equations(Pr (Prandtl number), Sc (Schmidt number), Nb (Brownian motion parameter), Nt (Thermophoresisparameter), λ=b/a (ratio of the stretching rate along y to x directions) and n (power-law index)),are discussed on the velocities, temperature, and nanoparticles concentration functions.As an important outcome, increasing both n and λ parameters, makes a reduction in shear stress,while it increase the Nusselt number function of heat transfer.
