...Dengqian Ma; Zhigang Li; Jun Li The leakage flow characteristics of the variable bristle diameter (VBD) brush seals are numerically investigated using the three-dimensional (3D) tube bundle model with consideration of bristle pack stratification. The discretization of the computational domain...

... leakage and smaller possibility of abrasion when the seal rotor–stator rubs in comparison to smooth plain seals. This paper deals with the static and rotordynamic characteristics of parallelly grooved liquid annular seals, which are limited in the literature. Numerical results of leakage flow rates, drag...

...Xiaozhi Kong; Yuxin Liu; Gaowen Liu; David M. Birch; Longxi Zheng As performance improvements of compressors become more difficult to obtain, the optimization of stator well structure to control the reverse leakage flow is a more important research subject. Normally, the stator well can...

...Zhigang Li; Jun Li; Xin Yan; Zhenping Feng Effects of pressure ratio and rotational speed on the leakage flow and cavity pressure characteristics of the rotating staggered labyrinth seal were investigated by means of experimental measurements and numerical simulations. The rotating seal test rig...

... in 1/16 in. honeycomb seal ( π = 1.1 ) Velocity vector distributions and Δ T total contours in 1/8 in. honeycomb seal ( π = 1.1 ) In order to investigate the influence of the cell depth on the leakage flow and total temperature increase...

...Jun Li; Shengru Kong; Xin Yan; Shinnosuke Obi; Zhengping Feng Three-dimensional Reynolds-averaged Navier–Stokes (RANS) solutions from CFX were utilized to investigate the leakage flow characteristics in the labyrinth honeycomb seal of steam turbines. At first, the accuracy and reliability...
