The present paper focuses on numerical study for an inclined magneto-hydrodynamic effect on free convection flow of a tangent hyperbolic nanofluid embedded with Carbon nanotubes (CNTs) over a stretching surface taking velocity and thermal slip into account. Two types of nanoparticles are considered for the study; they are single and multi-walled nanotubes. The presentation of single-parameter g...

We generalize the mode-coupling theory of supercooled fluids to systems under stationary shear flow. Our starting point is the generalized fluctuating hydrodynamic equations with a convection term. The method is applied to a two dimensional colloidal suspension. The shear rate dependence of the intermediate scattering function and shear viscosity is analyzed. The results show a drastic reductio...

We calculate solar models with convective overshooting at the top and at the base of the outer convection zone, and test the models by comparing their eigenfrequencies to the observed solar p-mode frequencies. Radiative temperature relaxation is included in form of a characteristic time that describes both optically thick and thin cases, and a modified mixing-length formalism is used, with gas ...

the fluid flow and heat transfer in lid-driven enclosures filled with cu-water nanofluid is numerically investigated. the moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity field and pressure in the momentum...

This paper presents a numerical investigation for laminar forced convection flow of a radiating gas in a rectangular duct with a solid element that makes a backward facing step. The fluid is treated as a gray, absorbing, emitting and scattering medium. The governing differential equations consisting the continuity, momentum and energy are solved numerically by the computational fluid dynamics t...

In this paper, we present a numerical study of turbulent natural-convection in square cavity differentially heated and filled with nanofluid subjected to an inclined magnetic field. The standard k-? model was used as the turbulence model. transport equations were discretized by finite volume method using SIMPLE algorithm. influence Rayleigh number, Hartmann orientation angle applied field, type...

Abstract We study the properties of oscillatory double-diffusive convection (ODDC) in presence a uniform vertical background magnetic field. ODDC takes place stellar regions that are unstable according to Schwarzschild criterion and stable Ledoux (sometimes called semiconvective regions), which often predicted reside just outside core intermediate-mass main-sequence stars. Previous hydrodynamic...

ABSTRACT The neutrino-driven wind from proto-neutron stars is a proposed site for r-process nucleosynthesis, although most previous work has found that heated only by neutrinos cannot produce the third peak. However, several groups have noted introducing secondary heating source within can change hydrodynamic conditions sufficiently strong to proceed. One possible gravito-acoustic waves, genera...

Recent measurements of Jupiter's gravitational moments by the Juno spacecraft and seismology Saturn's rings suggest that primordial composition gradients in deep interior these planets have persisted since their formation. One possible explanation is presence a double-diffusive staircase below planet's outer convection zone, which inhibits mixing across deeper layers. However, hydrodynamic simu...
