Research Abstract

This article presents the similarity solutions for the steady two-dimensional Falkner–Skan boundary layer flow of a nanofluid
over wedge with convective boundary condition. The model used for the nanofluid is the one that incorporates the
variable viscosity and nanoparticle volume fraction parameter. Numerical results for the dimensionless velocity and temperature
as well as skin friction and Nusselt number are presented graphically for different values of the controlling parameters.
Four different types of nanoparticles, namely, copper (Cu), alumina (Al2O3), titania (TiO2) and silver (Ag) as well
as two different types of the base fluid, namely, water and ethylene glycol are considered. It is shown that the skin friction
and dimensionless heat transfer rate increase with an increase in nanoparticle volume fraction, wedge, viscosity and
convective parameters. Comparisons with the published results for the skin friction and Nusselt number are presented
and found to be in good agreement
