Computational analysis for scallop seals with sickle grooves, part II: Rotordynamic characteristics

Andriy Zahorulko et al.

Summary: This study compares the characteristics of scallop seals with smooth, labyrinth, and damper seals, investigating the flow physics and friction losses mechanism on dynamic characteristics and leakage rate, as well as studying the influence of seal geometry on friction losses and pressure drop values along the seal length. The study confirms the high dynamic characteristics and frequency dependencies of scallop seals.

Computational analysis for scallop seals with sickle grooves, part I: Leakage performance

Andriy Zahorulko et al.

Summary: The paper discusses the leakage rate characteristics of scallop seals with sickle grooves (SSSG) depending on seal geometry, utilizing Computational Fluid Dynamics (CFD) and Design of Experiment (DOE) techniques for analysis. Such a comprehensive approach using computational methods allows for improving and optimizing existing designs of scallop seals.
