Abstract [en]

The numerical model was established using the two-dimensional cross section of staggered tube bundle of bristles, and the flow field was numerically solved by Fluent. This work presents velocity of flow and the variation range of flow velocity under transient state at the-last bristles gap are much higher than those of the front row, which leads to severe wear of the last row of bristles; as the bristle row number increases, the leakage decreases rapidly, then decreases slowly; the leakage increases linearly with the increase of the pressure difference; the brush drag force slowly increases along the axial direction but increases significantly at the last row; the drag force increases linearly with differential pressure increasing. © Springer Nature Singapore Pte Ltd 2019.
