      Sun, Junfeng; Liu, Meihong; Xu, Zhen; Liao, Taohong; Hu, Xiangping (Peer reviewed; Journal article, 2020)
      Gas film seal technology is becoming increasingly important as an advanced new rotary shaft seal technology in aviation engines and industrial gas turbines. In this paper the impacts of several parameters of T-groove ...
    • Numerical Analysis of Flow across Brush Elements Based on a 2-D Staggered Tube Banks Model 

      Song, Xiaolei; Liu, Meihong; Hu, Xiangping; Wang, Xueliang; Liao, Taohong; Sun, Junfeng (Journal article; Peer reviewed, 2021)
      n order to improve efficiency in turbomachinery, brush seal replaces labyrinth seals widely in the secondary air system. A 2-d staggered tube bank model is adopted to simulate the gas states and the pressure character in ...
