Unsteady magnetohydrodynamics (MHD) flow of fractionalized second grade nanofluid (Ag-Cu) over a vertical plate is obtained. The model solved by using CPC fractional derivative. novelty present study to generalized the Fourier’s and Fick’s laws. nanofluids are formed dispersing two different nanoparticles, silver (Ag) copper (Cu), into based fluid. governing dimensionless equations for velocity...

Abstract The evolution of unsteady gravitational-capillary convection in a layer ethyl alcohol with free surface after sudden electric heating one the vertical walls rectangular cavity was investigated numerically. effect incoming flow hot liquid on time temperature field opposite thin metal wall investigated. calculations were carried out by finite element method conjugate two-dimensional form...

A theoretical study of radiation heat transfer with reference to an optically thick fluid past oscillating vertical flat plate variable temperature in the presence convection and has been presented. The is considered be a gray, absorbing-emitting but non- scattering medium. Rosseland flux approximation plays important role determining effect contribution. This problem improvement Stoke’s first ...

This paper presents numerical simulations for a MHD convective process in curved channels. The worked suspension consists of water as based hybrid nanofluid and two types the nanoparticles, namely, Cu Al2O3. Two systems governing equations are formulated dusty phases. system is modeled view lubrication approach. mapped to regular computational domain then they solved numerically using fourth or...

A solution of unstable MHD free convective flow an incompressible, viscous and electrically steering fluid created by spontaneous motion vertical plate subjected to constant heat fluctuation offered Sacheti<em> et al.</em> has been revisited. The governing equations are deciphered with the aid Laplace transform procedure, while inversion is gotten through Riemann sum approximation a...

(Received ?? and in revised form ??) A comprehensive study of the effect of wall heating or cooling on the linear, transient and secondary growth of instability in channel flow is conducted. The effect of viscosity stratification, heat diffusivity and of buoyancy are estimated separately, with some unexpected results. ¿From linear stability results, it has been accepted that heat diffusivity do...

In this study, we investigated numerically heat transfer by mixed convection coupled to radiation in a square cavity; the upper horizontal wall is movable. The purpose of this study is to see the influence of the emissivity ε and the varying of the Richardson number Ri on the variation of average Nusselt number Nu. The vertical walls of the cavity are differentially heated, the left wall is mai...

In this numerical study, the effect of quartic autocatalysis type chemical reaction, buoyancy force and thermal radiation phenomenon magnetic on tangent hyperbolic nanofluid past an upper horizontal surface a paraboloid has been studied. By considering Buongiorno model approach, diffusion unequal coefficients in presence gyrotactic microorganism is discussed. Implementation microorganism's idea...

The study of mass transfer in the non-Newtonian fluid is essential understanding engine lubrication, cooling system electronic devices, and manufacturing process chemical industry. Optimal performance practical applications requires appropriate conditions. unsteady transient free convective flow second-grade with wall transpiration concerned present communication. behavior under influence injec...
