چکیده

Abstract An analysis into the transient natural convective flow of a nanofluid in vertical tube is made. The governing equations momentum, heat transfer and nanoparticle volume fraction are deduced, influence thermophoresis parameter Brownian motion incorporated. By direct integration variation parameter, analytical solutions obtained for formation heat/mass at steady-state. On other hand, due to complexity same problem state, numerical solution used solve discretized using implicit finite difference technique. noted well discussed. For accuracy check, comparison made between steady state large time; this gives an excellent agreement. role various principal parameters on velocity profile, temperature, concentration nanoparticles, Sherwood Nusselt numbers presented graphically It that buoyancy ratio decreases fluid significantly.

Transient MHD Convective Flow of Fractional Nanofluid between Vertical Plates

Effects of the uniform transverse magnetic field on the transient free convective flows of a nanofluid with generalized thermal transport between two vertical parallel plates have been analyzed. The fluid temperature is described by a time-fractional differential equation with Caputo derivatives. Closed form of the temperature field is obtained by using the Laplace transform and fractional deri...

DTM- Padé Modeling of Natural Convective Boundary Layer Flow of a Nanofluid Past a Vertical Surface

In this paper, we study theoretically the natural convective boundary-layer flow of a nanofluid past a vertical plate. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis. A similarity solution is developed. The similarity transformations are applied to reduce the governing partial differential equations to a set of nonlinear coupled ordinary differen...

Convective Heat Transfer of Oil Based Nanofluid Flow Inside a Circular Tube

Abstract   An empirical investigation was carried out to study convective heat transfer of nanofluid flow inside an inclined copper tube under uniform heat flux condition. Required data are acquired for laminar and hydrodynamically fully developed flow inside round tube. The stable CuO-base oil nanofluid with different nanoparticle weight fractions of 0.5%, 1% and 2% was produced by means of ul...
