Mixed Convection Magnetic Nanofluid Flow past a Rotating Vertical Porous Cone [PDF]
Journal of Applied Fluid Mechanics, 2022 Magnetic nanofluids (MNFs) have been the focus of extensive research nowadays owing to their potential usefulness as a transfer medium. This study is concerned with the boundary layer flow and heat transfer of MNF past a rotating vertical cone with the ...

Asteroseismology of Massive Stars : Some Words of Caution [PDF]
, 2014 Although playing a key role in the understanding of the supernova phenomenon, the evolution of massive stars still suffers from uncertainties in their structure, even during their "quiet" main sequence phase and later on during their subgiant and helium ...

Mixed thermal convection: fundamental issues and analysis of the planar case
Anais da Academia Brasileira de Ciências, 2015 This paper aims to renew interest on mixed thermal convection research and to emphasize three issues that arise from the present analysis: (i) a clear definition of the reference temperature in the Boussinesq approximation; (ii) a practical delimitation ...

Unsteady MHD Mixed Convection Flow of Water over a Sphere with Mass Transfer [PDF]
Journal of Applied and Computational Mechanics, 2021 This paper examines the unsteady magnetohydrodynamic (MHD) mixed convection flow over a sphere combined with variable fluid properties. An implicit finite difference scheme, together with the quasi-linearization, is used to find non-similar solutions for

Convergence of the Generalized Volume Averaging Method on a Convection-Diffusion Problem: A Spectral Perspective [PDF]
, 2005 A mixed formulation is proposed and analyzed mathematically for coupled convection-diffusion in heterogeneous medias. Transfer in solid parts driven by pure diffusion is coupled with convection-diffusion transfer in fluid parts.

Convective core mixing: A metallicity dependence? [PDF]
Astronomy & Astrophysics, 2002 The main scope of this paper is to investigate the possible existence of a metallicity dependence of the overshooting from main sequence stars turbulent cores. We focus on objects with masses in the range ~2.5 Msol - ~25 Msol. Basically, evolutionary time scale ratios are compared with star numbers ratios on the main sequence.
