Abstract

In this paper, an analysis is made for heat transfer unsteady flow of nanofluid over semi-infinite vertical plate with leading edge accretion/ablation. The impact of viscous dissipation in energy equation with Newtonian heating condition is also considered. Tiwari-Das model is used to incorporates the effects of nanoparticles volumetric fraction. Sodium carboxymethyl cellulose (SCMC) is considered as based fluid containing titania (TiO 2 ) nanoparticles. Similarity transformations are employed to transform the unsteady partial differential equations into a system of ordinary differential equations. The transformed equations along with relevant boundary conditions are solved numerically by Runge Kutta Fehlberg fourth-fifth order (RKF45) method in MAPLE software. The analysis shows that velocity and temperature field in the respective boundary layers depend on different physical parameters, namely Prandtl number, Eckert number, Casson parameter, Newtonian heating parameter, accretion/ablation parameter and nanoparticle volume fraction. Temerature shows higher value for Blasius flat plate, while for Rayleigh-Stokes is the lowest.

... The deposition characteristics of nanosized particle in convectional straight tube, a 90°90°s quare bend tube, the sodium caboxymethyl cellulose, including the titania nanoparticles in unsteady flow of based nanofluid, the angular momentum and microinertia characteristics on solid sphere, over vertical plate have been investigated by Ramirez-Tijerina et al., 8 Hussanan and Nguyen, 9 Swalmeh et al., 10 Yin et al., 11 and Abid et al. 12 Furthermore, the effects of Biot number with thermal convection on non-Newtonian fluid over an isothermal sphere, the effects of mixed convection on micropolar nanofluid containing oxide nanoparticles, and natural convection of nanofluid in a porous medium past heated vertical plate have been examined by Pop, 13 Gaffar et al., 14 Hamzeh et al., 15 and Ghalambaz et al. 16 The results demonstrate that enlarge values of mixed convection constraint and nanoparticle volume fraction enhance thermal convection and reduce local skin friction in methanol and kerosene oil-based nanofluid. As the thermal volumetric expansion boost due to the buoyancy force, which fall the density of fluid acts the skin friction coefficients reduce. ...

Buoyancy‐determined steady, laminar nonlinear convection flow of micropolar nanofluid with Soret effect, viscous dissipation over a cylinder were evaluated numerically using method bvp4c from matlab software for assorted quantities of leading parameters. Mathematical modeling for the flow problem has been completed with fitting resemblance change and dimensionless variable. A variable similarity solution is offered that bases on various quantities of leading parameters. Influences of these parameters on θ ″ ( 0 ) , − h ' ( 0 ) , ϑ ' ( 0 ) , − ϕ ' ( 0 ) are tested and displayed with the charts and graphs. The convergence test has been continued; for quantity of spots larger than suitable mesh number of points. The correctness is unchanged, but it takes time. Also, a comparison with prior study reachable in the literature has been offered with very good conformity is got. The findings show that the existence of Soret number agrees to enhance concentration profile ϕ ζ , Wall couple stress coefficient − h ′ 0 , θ ″ 0 , and Nusselt number – ϑ ′ ( 0 ) . But the presence of Eckert Number Ec, allows declining velocity, microrotation, temperature, and concentration profiles.

This research article is design to elaborate the rule and signifi�cance of fractional derivative for heat transport in drilling of Casson nanofluid. The obtained governing equations with integer order derivative extended to the model with non-integer order derivative and then solved analytically for temperature and velocity �field with the help of Laplace transform method. The obtained solutions for temperature and velocity are presented geometrically by Mathcad software to see the effectiveness of flow parameters. The fluid properties show a signi�cant trend for increasing volume fraction parameter. The obtained results for temperature as well as velocity are also compared with the existing literature and it is concluded that �field variables with new fractional derivative, show more decaying trend in the memory sense as compare to the results with Caputo and Caputo-Fabrizio fractional derivatives respectively.

In the present research analysis we have addressed comparative investigation of radiative electrically conducting Casson nanofluid. Nanofluid Flow is assumed over a nonlinearly stretching sheet. Heat transport analysis is carried via joule dissipation, thermal behavior and convective boundary condition. To employ the radiative effect radiation was involved to show the diverse states of nanoparticles. Furthermore entropy optimization with activation energy and chemical reaction are considered. Thermodynamics 2nd law is applied to explore entropy generation rate. Nonlinear expression is simplified through similarity variables. The reduced ordinary system is tackled through optimal approach. Flow pattern was reported for wide range of scrutinized parameters. Computational consequences of velocity drag force, heat flux and concentration gradient are analyzed numerically in tables. Results verify that conduction mode augments with enhance of magnetic parameter.Increasing radiation boosts the temperature and entropy. Activation energy corresponds to augmented concentration. Heat transmission rate augments with the consideration of radiation source term.
