“…The stretching or shrinking is due to the impulsive force that acts in x-direction (+ve or -ve). The findings in the case of Cu-water nanofluid are similar to the result obtained by Grosan and Pop [29].…”

We study the unsteady convective flow of two water-based nanofluids containing Copper and Titanium oxide along a vertical stretching or shrinking cone with viscous dissipation and internal heat generation. The problem is transformed to two-dimensional flow over a cone using Mangler's transformation. The coupled nonlinear conservation equations are solved numerically using the spectral local linearization method. We present an analysis of how some physical parameters affect the flow structure, the heat and mass transfer rates and the fluid properties. The accuracy of the results is determined by comparison with previously published studies, for some limiting cases.

“…Lok et al [4] showed the mixed convection flow for both stretching and shrinking cylinder by considering the stagnation point. Anwar et al [5] discussed the steady mixed convection flow over a horizontal circular cylinder, and Grosan and Pop [6] studied the axisymmetric mixed convection boundary layer flow past a thin vertical cylinder placed in a water-based copper nanofluid. Nazar et al [7] has reported the laminar mixed convection boundary layer flow past a horizontal circular cylinder, which is maintained at a constant heat flux.…”

“…Grosan and Pop [8] theoretically investigated axisymmetric free-forced convection water-based ow along a standing cylinder in the presence of copper nanoparticles with a xed surface temperature and external ow. The study on stretching/shrinking movement in a mixed convection of both assisting and opposing ows along a vertical cylinder was done by Lok et al [9].…”

Abstract. The axisymmetric ow of a nanoparticles-saturated uid with existence of thermic radiation over a stretched sheet is investigated. The e ects of zero (passive control) as well as nonzero uxes (active control) of nanoparticles on the plate on distributions of temperature and volumetric fraction of nanoparticles are investigated together comparatively. Through the supposition of boundary layer, the Navier-Stokes equations are simpli ed hence converted into non-dimensional form by similarity transformation. A shooting technique is engaged to deal with the emerging nonlinear system of ordinary di erential equations numerically in MATLAB software. Several distributions of velocity, thermal energy, and volumetric fraction of nanoparticles under zero/nonzero normal ux are graphically demonstrated. The impact of the parameters on the reduced coe cient of skin friction, Nu r and Sh r , are also investigated. The presence of thermic radiation under consideration of both zero and nonzero normal uxes has signi cant e ects on the intensi cation of the ow heat transfer. Thermophoresis enhances the heat conductivity performance in the case of zero uxes of nanoparticles.
