ABSTRACT How should we understand the duration of a pleasant or unpleasant sensation, insofar as its duration modulates how good or bad the experience is overall? Given that we seem able to distinguish between subjective and objective duration and that how well or badly someone's life goes is naturally thought of as something to be assessed from her ...

To investigate the transient characteristics of high-speed axial flow water-jet pumps during start-up and emergency acceleration as well as to analyze how different accelerations affect the performance of internal flow, the k–ω turbulence model of the ...

This work shows that A‐site composition dictates the restructuring of Ruddlesden–Popper nickelate oxides (A2‐xA’xNiO4; A = La, Eu, Gd; A’ = Sr; x = 0–1.5) under alkaline oxygen evolution reaction conditions and suggests that electrocatalytic stability is governed by an interplay between dissolution‐mediated site exposure and Ni oxidation state ...

ABSTRACT Ethically responsible and culturally acceptable management, study, and stewardship of legacy skeletal and other human remains currently held and managed in scientific institutions is a longstanding concern that, over the length of these collections' existence, has been exiguously addressed.

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

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

ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects
