• Cavity flows and wake behind an elliptic cylinder translating above the wall 

      Zhu, Jianxun (Doctoral theses at NTNU, 2020:312, Doctoral thesis, 2020)
      Vortex formation is one of the fundamental modes in fluid mechanics and it can develop in almost every realization of fluid motion. Studying its fundamental dynamics and interactions is of great interest for engineering ...
    • Effects of an inserted circular cylinder on a steady lid-driven rectangular cavity flow 

      Zhu, Jianxun; Holmedal, Lars Erik; Myrhaug, Dag (Journal article; Peer reviewed, 2019)
      This paper provides numerical investigations of flow in a steady lid-driven cavity of depth to width ratio 1/3 containing a circular cylinder. The inner cylinder is treated using a direct-forcing immersed boundary method, ...
    • Flow patterns in a steady lid-driven rectangular cavity with an embedded circular cylinder 

      Zhu, Jianxun; Holmedal, Lars Erik; Wang, Hong; Myrhaug, Dag (Peer reviewed; Journal article, 2020)
      A detailed investigation of the flow in a steady lid-driven cavity of depth to width ratio 1:2 containing a circular cylinder is provided. Three different Reynolds numbers (based on the lid velocity and cavity depth) of ...
    • Fluid flow in steady and oscillatory lid-driven square cavities 

      Zhu, Jianxun; Holmedal, Lars Erik; Myrhaug, Dag; Wang, Hong (Peer reviewed; Journal article, 2017)
      This paper presents numerical simulations of steady and oscillatory lid-driven cavity flow at different Reynolds numbers with a fixed aspect ratio of 1:1. A projection method (P2 pressure correction method) is applied to ...
    • Near-wall effect on flow around an elliptic cylinder translating above a plane wall 

      Zhu, Jianxun; Holmedal, Lars Erik; Myrhaug, Dag; Wang, Hong (Peer reviewed; Journal article, 2020)
      In this work, the flow over an elliptic cylinder near a moving wall is investigated for Reynolds numbers less than 150. Here, the ratio between the gap (i.e., the distance between the cylinder and the wall) and the length ...
    • Three-dimensional wake transition behind an elliptic cylinder near a moving wall 

      Zhu, Jianxun; Jiang, Fengjian; Holmedal, Lars Erik (Peer reviewed; Journal article, 2021)
      In this work, the flow over an elliptic cylinder near a moving wall is investigated for Reynolds numbers less than 150. Here, the ratio between the gap (i.e., the distance between the cylinder and the wall) and the length ...
