Seals in turbomachinery have a huge impact on efficiency. The labyrinth seal a with
honeycomb land is one of the most popular solutions applied in gas turbines to control …

The positive circumferential flow is the major cause of seal instability. This paper proposes
the airfoil guider seal (AGS) with specially designed airfoil guiders in cavities. The pressure …

The honeycomb seal is a vital component to reduce the leakage flow and improve the
system stability for the turbomachines. In this work, a three-dimensional model is established …

The various lengths, clearances, numbers, and rotation angles of swirl brakes are
investigated to evaluate their effects on the static and rotordynamic performance of the …

Power generation has been and remains a focal point of economic, environmental,
sociological, and ethical discourse in the field of engineering. In recent times, there has …

The circumferential spiral flow is the main cause of destabilizing tangential force. To control
the circumferential spiral flow, the helix-comb seal is presented in this study. With the …

Swirl brakes are usually introduced at the seal entrance in industry to improve the seal
stability, especially for labyrinth seals suffering low seal clearance and high inlet preswirl …

The positive circumferential flow is the main cause of seal instability in turbomachines. This
paper proposed an annular gas seal with self-adaptive jet slots (SJS). The anti-swirl jet …

Introducing a negative preswirl at the upstream of annular gas seals has been considered
as an effective way to improve the system stability. This paper demonstrates a stability …

The numerical solution model of the labyrinth seal considering the multiple frequencies
elliptical whirling of the rotor and swirl brake was established by the computational fluid …
