The flow of a second grade fluid by a rotating stretched disk is considered. Brownian motion and thermophoresis characterise the nanofluid. Entropy generation in the presence of heat generation / absorption, Joule heating and nonlinear thermal radiation is discussed. Homotopic convergent solutions are developed. The behaviour of velocities (radial, axial, tangential), temperature, entropy generation,...
Peristaltic pumping of Sisko fluid through the non-uniform asymmetric channel is addressed. Main motivations are given to nonlinear radiation and inclined magnetic field. The perturbation technique and lubrication approach are utilized for development of governing problems and solutions. Resulting equations are solved for velocity, temperature, pressure and stream function. Trapping phenomenon is...
This article addresses unsteady stagnation point flow of Oldroyd-B nanofluid past an impermeable stretching sheet. Characteristics of heat transfer are described within the frame of heat generation/absorption and nonlinear radiative process. Intention in present analysis is to develop a model for nanomaterial containing Brownian motion and thermophoresis phenomena. The resulting nonlinear differential...
