Investigation of Flow through a Labyrinth Seal [PDF]
INCAS Bulletin, 2021 Growing performance requirements for gas turbines have led to a continuous increase in gas temperature and pressure ratios. Together with the resulting increase in cooling flows, this requires more and more minimization and control of internal gas leaks.

Measured Air Flow Leakage in Facemask Usage
International Journal of Environmental Research and Public Health, 2023 The importance of wearing a facemask during a pandemic has been widely discussed, and a number of studies have been undertaken to provide evidence of a reduced infectious virus dose because of wearing facemasks. Here, one aspect that has received little attention is the fraction of breathing flow that is not filtered because it passes as leak flow ...

Influence of flow pattern on leakage acoustic signal of multiphase pipeline
You-qi chuyun, 2021 In order to solve the problem that it is difficult to apply the existing leakage detection mechanism of singlephase pipelines with no consideration to the influence of flow patterns to the multiphase pipelines, the theoretical study and test analysis ...

Retrograde Flow Cement Leakage during Kyphoplasty
Maedica - A Journal of Clinical Medicine, 2022 Objective: To report a rare event of a retrograde flow of cement leakage during balloon kyphoplasty and discuss the possible mechanism. Methods:We present a 55-year-old male patient, who underwent a 4-level balloon kyphoplasty for Langerhans histiocytosis that had spread to the spine.
