A test of time-dependent theories of stellar convection [PDF]
, 2011 Context: In Cepheids close to the red edge of the classical instability strip, a coupling occurs between the acoustic oscillations and the convective motions close to the surface.The best topical models that account for this coupling rely on 1-D time ...

Laminar mixed convection of Cu-water nano-fluid in two- sided lid-driven enclosures [PDF]
Journal of Nanostructures, 2011 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.

Destabilization of free convection by weak rotation [PDF]
, 2011 This study offers an explanation of a recently observed effect of destabilization of free convective flows by weak rotation. After studying several models where flows are driven by a simultaneous action of convection and rotation, it is concluded that ...

From zonal flow to convection rolls in Rayleigh–Bénard convection with free-slip plates [PDF]
Journal of Fluid Mechanics, 2020 Rayleigh–Bénard (RB) convection with free-slip plates and horizontally periodic boundary conditions is investigated using direct numerical simulations. Two configurations are considered, one is two-dimensional (2-D) RB convection and the other one three ...

Free convection on a refrigerator’s condenser
EPJ Web of Conferences, 2014 The paper presents the measurement of heat transfer coefficient for the refrigerator’s condenser in free convection regime. The water was pumped through the steel coils of heat exchanger with a constant flow rate and its temperature was kept at a ...
