By means of He's homotopy perturbation method (HPM) an approximate solution of velocity eld is derived for the ow in straight pipes of non-Newtonian uid obeying the Sisko model. The nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to He. Furthermore, the obtained solutions for velocity eld is graphically sketched...

Porous materials manufactured by freeze-casting are demonstrating potential application as oxygen carriers for the production and purification of hydrogen, or anode material lithium-ion batteries. However, to obtain required pore morphology sufficient mechanical strength, suspension processing parameters must be controlled. Fe2O3 nanoparticles/camphene suspensions were fabricated using stearic ...

The major focus of this article is to analyze the forced convective heat transfer in a steady boundary layer flow of Sisko fluid over a nonlinear stretching sheet. Two cases are studied, namely (i) the sheet with variable temperature (PST case) and (ii) the sheet with variable heat flux (PHF case). The heat transfer aspects are investigated for both integer and non-integer values of the power-l...

The current analysis provides the important insights of Sisko nanofluid flow over a wedge with thermal radiation and viscous dissipation effects. Buongiorno model, which includes Brownian movement thermophoresis, is taken into consideration. Momentum, temperature, nanoparticle concentration equations are used to simulate problem. suitable similarity variables applied governing partial different...
