Experimental and Numerical Investigation of a Novel Vortex Reducer in a Co-Rotating Cavity of Aeroengines

Aerospace
Improving airflow pressure is of great significance for the cooling and sealing of aeroengines. In a co-rotating cavity with radial inflow, vortex reducers are used to decrease the pressure drop. However, the performance of traditional vortex reducers is

Reasoning without consensus: grassroots experiments in radical inclusion in Israel/Palestine Raisonner sans consensus : expériences locales d'inclusion radicale en Israël et en Palestine

Journal of the Royal Anthropological Institute, Volume 31, Issue 4, Page 1079-1097, December 2025.
Liberal public reason seeks to provide a neutral platform for political engagement. Yet, its conditions, notably the rules of engagement and the demand for consensus, effectively exclude many populations with non‐liberal subjectivities from public participation.

Characteristics of rotating instability in a centrifugal blower with shrouded impeller

Transactions of the JSME (in Japanese), 2014
The Rotating instability, abbreviated to RI, in a centrifugal blower with shrouded impeller is investigated by experiments and CFD analyses. The RI occurs in a partial-flow operation of the blower prior to stall with mild fluctuations of impeller-discharge velocity and radiated noise, and appears in the power spectra as a gradual hump at almost half of

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1394-1403, November 2025.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration
