Abstract

A parametric study of the skin friction coefficient and drag force of Titania/water nanofluid flow over an isothermal flat plate at stationary condition is conducted. With the help of similarity analysis, the governing equations of continuity and momentum are reduced into nonlinear differential equations which are subsequently solved numerically using a shooting method in Engineering Equation Solver (EES) software. The effect of volume fraction on the different flow parameters is evaluated. The numerical results show that density and dynamic viscosity increase with increase in particle volume fraction of nanoparticles. The thickness of hydrodynamic boundary layer reduced with an increase in nanoparticle volume fraction in base fluid. Skin friction coefficient and wall shear stress increase in magnitude with the inclusion of nanoparticles in base fluid but decrease along the direction of flow. The results are displayed graphically and they contribute to understanding the interesting aspects of nanofluids.
