    • On heat transfer in Bödewadt flow 

      Rahman, Muhammad; Andersson, Helge Ingolf (Journal article, 2017)
      Heat transfer in revolving Bo¨dewadt flow above a planar surface has been considered. We have shown that a similarity solution of the thermal energy problem does not exist as long as the surface is impermeable. The failure ...
    • On vortex shedding from a hexagonal cylinder 

      Khaledi, Alidoosti Hatef; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2011)
    • Particle segregation in turbulent Couette-Poiseuille flow with vanishing wall shear 

      Yang, Kun; Zhao, Lihao; Andersson, Helge Ingolf (Journal article, 2017)
      Inertial particles dispersed in wall-bounded flows in pipes and channels are known to accumulate close to the walls. The segregation ability depends greatly on the inertia-selection effects of the near-wall quasi-coherent ...
    • Preferential orientation of tracer spheroids in turbulent channel flow 

      Jie, Yucheng; Zhao, Lihao; Xu, Chunxiao; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2019)
      Axis-symmetric spheroids, such as rod-like and disk-like particles, have been found to orient preferentially in near-wall turbulence by both experiment and numerical simulation. In current work we examined the orientation ...
    • Preferential particle concentration in wall-bounded turbulence with zero skin friction 

      Yang, Kun; Zhao, Lihao; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2017)
      Inertial particles dispersed in turbulence distribute themselves unevenly. Besides their tendency to segregate near walls, they also concentrate preferentially in wall-parallel planes. We explore the latter phenomenon in ...
    • Recent Developments and New Results on The Flow Around an Inclined 6:1 Prolate Spheroid 

      Strandenes, Håkon; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Chapter, 2017)
      In the light of new computational resources and improved simulation tools we present new simulations of the flow around an inclined 6:1 prolate spheroid. We present the development of the flow from the symmetric and laminar ...
    • Revolving flow of a fluid-particle suspension with suction 

      Rahman, Muhammad; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2018)
      The three-dimensional revolving flow of a particle-fluid suspension above a plane surface is considered. The flow represents an extension of the classical Bödewadt flow to a two-fluid problem. The governing equations for ...
    • Simple Geometry – Complex Flow A computational study of turbulent particle-laden flows impinging on a cylinder 

      Aarnes, Jørgen Røysland (Doctoral theses at NTNU;2018:307, Doctoral thesis, 2018)
      Direct numerical simulations were performed to study the effects of free-stream turbulence on different flow regimes past a circular cylinder. The focus was on the transition-in-wake state of the flow and particle impact ...
    • Simulering av turbulent swirlstrømning gjennom et dobbelt rørbend 

      Moe, Kjetil Birkeland (Master thesis, 2010)
      Numeriske simuleringer blir utført for å undersøke hvordan swirlstrømning kan bidra til trykktapsreduksjon over rørbend. Fire individuelle sammenligninger gjøres først mot publiserte eksperimentelle data av Eggels, Wu & ...
    • Turbulent Couette–Poiseuille flow with zero wall shear 

      Yang, Kun; Zhao, Lihao; Andersson, Helge Ingolf (Journal article, 2017)
      A particular pressure-driven flow in a plane channel is considered, in which one of the walls moves with a constant speed that makes the mean shear rate and the friction at the moving wall vanish. The Reynolds number ...
