A threedimensional study of the onset of convection in a horizontal, rectangular porous channel heated from below
Barletta, Antonio; Storesletten, Leiv (Journal article; Peer reviewed, 2012)The onset of convection is studied in a rectangular channel filled with a fluid saturated porous medium, bounded above and below by impermeable isothermal walls at unequal temperatures and laterally by partially conducting ... 
Convective instability in a horizontal porous channel with permeable and conducting side boundaries
Barletta, Antonio; Rossi di Schio, Eugenia; Storesletten, Leiv (Journal article; Peer reviewed, 2013)The stability analysis of the motionless state of a horizontal porous channel with rectangular crosssection and saturated by a fluid is developed. The heating from below is modelled by a uniform flux, while the top wall ... 
Convective Roll Instabilities of Vertical Throughflow with Viscous Dissipation in a Horizontal Porous Layer
Barletta, Antonio; di Schio, Eugenia Rossi; Storesletten, Leiv (Journal article; Peer reviewed, 2010)The vertical throughflow with viscous dissipation in a horizontal porous layer is studied. The horizontal plane boundaries are assumed to be isothermal with unequal temperatures and bottom heating. A basic stationary ... 
Effect of a finite external heat transfer coefficient on the DarcyBenard instability in a vertical porous cylinder
Barletta, Antonio; Storesletten, Leiv (Journal article; Peer reviewed, 2013)The onset of thermal convection in a vertical porous cylinder is studied by considering the heating from below and the cooling from above as caused by external forced convection processes. These processes are parametrised ... 
Linear instability of mixed convection of cold water in a porous layer induced by viscous dissipation
Storesletten, Leiv; Barletta, Antonio (Journal article; Peer reviewed, 2009)An analysis of linear stability of the stationary laminar Darcy flow in a horizontal porous layer is performed. The porous layer is saturated with cold water. The upper plane boundary is assumed to be subject to heat ... 
On the thermal instability in a horizontal rectangular porous channel heated from below by a constant flux
Barletta, Antonio; Rossi di Schio, Eugenia; Storesletten, Leiv (Journal article; Peer reviewed, 2014)The onset of thermoconvective instability in a rectangular horizontal channel filled with a fluidsaturated porous medium is studied. The channel is heated from below with a constant flux. The top wall is maintained at a ... 
Onset of convection in a porous rectangular channel with external heat transfer to upper and lower fluid environments
Barletta, Antonio; Storesletten, Leiv (Journal article; Peer reviewed, 2012)The conditions for the onset of convection in a horizontal rectangular channel filled with a fluid saturated porous medium are studied. The vertical sidewalls are assumed to be impermeable and adiabatic. The horizontal ... 
Stability of Flow with Viscous Dissipation in a Horizontal Porous Layer with an Open Boundary Having a Prescribed Temperature Gradient
Barletta, Antonio; Storesletten, Leiv (Journal article; Peer reviewed, 2010)A buoyancyinduced stationary flow with viscous dissipation in a horizontal porous layer is investigated. The lower boundary surface is impermeable and subject to a uniform heat flux. The upper open boundary has a prescribed, ... 
Viscous dissipation and thermoconvective instabilities in a horizontal porous channel heated from below
Barletta, Antonio; Storesletten, Leiv (Journal article; Peer reviewed, 2010)A linear stability analysis of the basic uniform flow in a horizontal porous channel with a rectangular cross section is carried out. The thermal boundary conditions at the impermeable channel walls are: uniform incoming ...
