Zero and nonzero normal fluxes of thermal radiative boundary layer flow of nanofluid over a radially stretched surface

Abstract

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.

A study on nanoliquid flow with irregular heat source and realistic boundary conditions: A modified Buongiorno model for biomedical applications

“…The nanofluid is modeled using the MBM and experimentally derived nanofluid models (for effective dynamic viscosity and effective thermal conductivity). The normal mass flow of the nanoparticles at the boundary is kept at zero (passive control of the nanoparticles [27][28][29]), which improves the practicality of the model. The radiative heat flux applied to the system is modeled using the Rosseland approximation (see [30]).…”

A Numerical Study of Dissipative Chemically Reactive Radiative MHD Flow Past a Vertical Cone with Nonuniform Mass Flux

“…Recently the following investigators [27][28][29][30][31][32][33] presented electrically conducting, magneto hydrodynamic transfer of heat in a specific medium like Maxwell fluid, micro polar, nanofluid, Maxwell nanofluid with or without viscous dissipation, heat generation, absorption and mass flux. Magneto hydrodynamic convection flow due to the impacts of external forces and heat transfer over ferrofluids along a moving plate with uniform heat flux and second-order slip effects, chemical reaction with MHD stagnation point flow in porous medium were presented by the researchers [36][37][38][39].…”

Thermophoresis and Brownian motion effects of nanoparticles on Radiative heat transfer in Hiemenz flow: Using Spectral Method

“…According to their study, below the start temperature of freezing, 10 C drop in substrate temperature causes a large increase in the ultimate thickness of the ice at fareld air temperature of 5 C, while it slightly increases the ultimate thickness of the ice at the air temperature of 20 C. Rana et al [35] considered hydrothermal characteristics of nano uid using KKL model with Brownian motion and recommended nano-uids as a better coolant than the base uid. Ramly et al [36] investigated active and passive control of nanoparticles for heat transfer over a stretching sheet under the e ect of thermic radiation. They stated that in the case of zero uxes of nanoparticles, thermophoresis would enhance heat conductivity performance.…”
