    • 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 ...

    • A Non-normal-Mode Marginal State of Convection in a Porous Rectangle 

      Tyvand, Peder A.; Nøland, Jonas Kristiansen; Storesletten, Leiv (Journal article; Peer reviewed, 2019)
      The fourth-order Darcy–Bénard eigenvalue problem for onset of thermal convection in a 2D rectangular porous box is investigated. The conventional type of solution has normal-mode dependency in at least one of the two spatial ...

    • Onset of Convection in a Triangular Porous Prism with Robin-Type Thermal Wall Condition 

      Tyvand, Peder A.; Nøland, Jonas Kristiansen (Journal article; Peer reviewed, 2019)
      This paper investigates a peculiar case of thermal convection in a vertical porous prism with impermeable and partially conducting walls. We facilitate the analysis in the numerical finite-element environment alongside ...

    • Oscillatory Non-normal-Mode Onset of Convection in a Porous Rectangle 

      Tyvand, Peder A.; Nøland, Jonas Kristiansen (Journal article; Peer reviewed, 2019)
      A special case of the fourth-order Darcy–Bénard problem in a two-dimensional (2D) rectangular porous box is investigated. The present eigenfunctions are of non-normal-mode type in the horizontal and vertical directions. ...
