In this paper, the scalings incorporating the Prandtl number (Pr) dependence have been obtained by a scaling analysis for the unsteady natural convection boundary layer of an initially quiescent...
Laminar plane fountains impinging on a ceiling with an opposing heat flux (2009)
Srinarayana, N., Armfield, S.W., Lin, Wenxian
The behaviour of unsteady planar strong fountains, impinging on a ceiling with an opposing heat flux on the ceiling, is investigated numerically for 8:0 6 Fr 6 30:0 at Re ¼ 50 and Pr ¼ 7. The...
Impinging plane fountains in a homogeneous fluid (2009)
Srinarayana, N., Armfield, S.W., Lin, W.X.
The transient behaviour of plane fountains with a uniform inlet velocity, injected upwards into a quiescent homogeneous fluid of lower density to impinge on a solid flat ceiling, is investigated. The...
Direct numerical simulation of turbulent intermediate Froude number fountain flow (2008)
Williamson, N., Armfield, S.W., Lin, W.
Fountains are an important flow in many industrial and geophysical problems but the understanding of this flow at low Froude numbers is limited. In this study we use direct numerical simulation to...
Lin, Wenxian, Armfield, S.W., Patterson, John C.
The flow behaviour associated with the cooling of an initially quiescent isothermal Newtonian fluid with Prandtl number Pr less than unity in a rectangular container by unsteady natural convection...
Lei, C., Armfield, S.W., Patterson, J.C., O'Neill, A.
This study is concerned with heat transfer by natural convection in a differentially heated square cavity. The purpose is to explore numerically the effects of the comer geometry and adiabatic...
Unsteady natural convection on an evenly heated vertical plate for Prandtl number Pr (2005)
The transient behavior of the natural convection boundary-layer flow adjacent to a vertical plate heated with a uniform flux in a quiescent homogeneous ambient fluid with Prandtl number Pr
Long-term behavior of cooling fluid in a rectangular container (2004)
In this study, the long-term behavior of cooling an initially quiescent isothermal Newtonian fluid in a rectangular container with an infinite length by unsteady natural convection due to a fixed...
Weak fountains in a stratified fluid (2002)
The behavior of weak axisymmetric and plane fountains resulting from the injection of denser fluid upwards into large containers containing a stably stratified fluid has been explored using...
