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.

Study of Charging Nitrogen to External Floating Roof Tank to Prevent Rim-seal Fires from Lightning
, 2014 It is estimated that 95% of rim seal fires are caused by lightning strikes. To avoid rim-seal fires caused by lightning, the existing methods mainly focus on the use of secondary sealing to reduce volatilization of oil and the electrical connections ...

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia
Insect Conservation and Diversity, EarlyView.Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula
Journal of Applied Entomology, EarlyView.ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.
