Abstract
Unsteady thin hybrid nanoliquid film flow over a stretchable cylindrical surface is studied with the uniform thickness of hybrid nanoliquid. The combined effects of different nanoparticles like single-walled carbon nanotubes (SWCNTs), multi-walled carbon nanotubes (MWCNTs) and copper (Cu) are considered for investigation in the presence of thermocapillarity, magnetic field and thermal radiation. The finite difference technique is applied to solve the governing set of nonlinear equations. Result showed that the hybrid nanoliquid film thinning rate declined with the higher volume fraction of different nanoparticles. The hybrid nanoliquid film thickness enhanced with higher values of radiation parameter and magnetic field. A curve [Formula: see text] is described within the hybrid nanoliquid film which separated total flow region in two zones. In one side of this curve, heat is transferred from the cylindrical surface to the hybrid nanoliquid film and in the other side, opposite scenario is observed.
