Numerical study on the effect of rim seal slot filleting on turbine endwall cooling
AIP AdvancesIn this study, the effect of rim seal slot filleting on turbine endwall film cooling performance is numerically investigated. For comparison with the baseline case, five different fillet radius and width (R/W) ratios are adopted, i.e., R/W = 1.25, 2.5, 3.

Nanoscale-targeted patch-clamp recordings of functional presynaptic ion channels [PDF]
, 2013 Important modulatory roles have been attributed to presynaptic NMDA receptors (NMDARs) located on cerebellar interneuron terminals. Evidence supporting a presynaptic location includes an increase in the frequency of mini events following the application ...

Aerodynamic performance of turbine rim sealing flows
, 2022 An investigation of the hot gas ingestion phenomenon in the Oxford Rotor Facility ex- amined rotor disc rotation, mainstream pressure asymmetries and unsteady structures in the cavity as main drivers. The facility underwent major modifications to allow different annulus flow configurations, higher resolution in the low and high bandwidth pressure ...

Measurement and Analysis of Ingestion Through a Turbine Rim Seal
Volume 3: Turbo Expo 2002, Parts A and B, 2002 Experimental measurements from a new single stage turbine are presented. The turbine has 26 vanes and 59 rotating blades with a design point stage expansion ratio of 2.5 and vane exit Mach number of 0.96. A variable sealing flow is supplied to the disc cavity upstream of the rotor and then enters the annulus through a simple axial clearance seal ...
