Numerical Analysis on the Effect of J-groove on Flows in Narrow Gaps between Rotating Disk and Casing
Nguyen Vo Dao, Matsui Jun
International Journal of Fluid Machinery and Systems 15 ( 1 ) 64 - 74 2022.1 [Reviewed]
Language：English Publishing type：Research paper (scientific journal) Publisher：ターボ機械協会、韓国流体機械学会、中国工程熱物理学会、国際水理学会 Joint Work
During operation and working of turbo machines, axial thrust balancing is important. To control and balance the axial thrust, a very simple method using shallow radial grooves mounted on the casing wall, called “J-groove”, was proposed, and studied experimentally[1]. This paper presents a numerical study of the effect of J-groove on the flow in the narrow gap along enclosed rotating disks based on open-source CFD software. It is seen that the difference in pressure between the hub and shroud tip is increased with the increasing number, depth, and length of J-groove. But in the case of increasing width of J-groove, the pressure loss along the radius decreases when the ratio of the groove width to the outer radius W is less than 0.2 and increases when W greater than 0.2.

Specific Internal Flow in Balancing Hole

Turbomachinery 47 ( 12 ) 723 - 729 2020.3 [Reviewed]

<p>In order to research the discharge coefficient of a balancing hole <i>C<sub>d</sub></i> for a wide range of axial flow velocity <i>v</i> in the hole and rotational speed <i>u</i>, we carried out CFD simulations. Some of the results and the reported experimental data agree within the difference of about 5.3% on the pressure difference of the hole. Flow in a balancing hole is influenced by not only <i>v</i> but also <i>u</i>. Therefore the parameter <i>v</i>/<i>u</i> is considered as an important parameter of <i>C<sub>d</sub></i>. Furthermore, for very low range of <i>v</i>/<i>u</i>, we found a rare flow situation with S-shaped streamlines. Due to the strong pumping effect by rotating disk, <i>C<sub>d</sub></i> is greatly different in this region.</p>
