OHAM analysis of Newtonian heating in mixed convective flow of CNTs over a stretched cylinder
Alexandria Engineering Journal, 2022 This work reports mathematical modeling and analysis of mixed convection flow of nanofluids with stagnation point by a stretching cylinder. Carbon nanotubes are dispersed as nanomaterial in the baseliquid of water.

Numerical Analysis of Turbulent Mixed Convection in Vertical Annular Channel
Yuanzineng kexue jishu, 2023 Reactor cavity cooling system (RCCS) is a competitive residual heat removal scheme for small modular reactors. In this paper, the RCCS has been simplified to a scenario that ascending air flow is got heated in vertical annular channels and driven by ...

Convective Mixing and the Thermohaline Circulation
Journal of Physical Oceanography, 1999 Abstract An idealized three-dimensional model of buoyancy-driven flow in a single hemisphere is used to investigate the relationship between the meridional overturning and the efficiency by which convective mixing eliminates static instability. In the “fast” limit (mixing timescale hours to weeks), the meridional overturning is not rate limited by the ...

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.

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 ...
