• A Non-normal-mode Marginal State of Convection in a Porous Box with Insulating End-Walls 

      Tyvand, Peder A.; Nøland, Jonas Kristiansen (Journal article; Peer reviewed, 2019)
      The 4th order Darcy-Benard eigenvalue problem for the onset of thermal convection in a 3D rectangular porous box is investigated. We start from a recent 2D model for a rectangle with hand-picked boundary conditions defying ...
    • Laterally Penetrative Onset of Convection in a Horizontal Porous Layer 

      Tyvand, Peder A.; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2020)
      The onset of Darcy–Bénard convection in an unlimited horizontal porous layer is studied theoretically. The thermomechanical boundary conditions of Dirichlet or Neumann type at the lower and upper plane are switched from ...
    • Non-normal-Mode Onset of Convection in a Vertical Porous Cylinder 

      Tyvand, Peder A.; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2020)
      This is the first study reporting a full three-dimensional (3D) non-normal-mode onset of convection in a porous medium. In this paper, the onset of thermal convection in a vertical porous cylinder is investigated theoretically. ...
