Abstract: The modeling and control of a recently developed utility-scale, shaftless, hubless, high strength steel energy storage flywheel system (SHFES) are presented. The novel flywheel is designed with an energy/power capability ...

Abstract: The high-speed rotation of impellers leads to strong rotor–stator interaction, which mainly causes the pressure pulsation of centrifugal pumps. An impeller with a bionic sinusoidal tubercle trailing edge (STTE) can reduce ...

Abstract: The impeller, which is the main energy conversion component of a pump as turbine (PAT), is designed for pumping mode, and its internal flow characteristics are quite complicated even at the best efficiency point (BEP) of ...

Abstract: The objective of this paper is to investigate the dynamic characteristics of transient cavitating flow over a twisted NACA0009 hydrofoil. The large eddy simulation (LES) approach is selected for the computation of fluid ...

Abstract: It has been recognized that cells are able to actively sense and respond to the mechanical signals through an orchestration of many subcellular processes, such as cytoskeleton remodeling, nucleus reorientation, and ...

Abstract: Theoretical research and earthquake damage investigation indicate that there is bend torsion coupling vibration for curved bridge when earthquake occurs. To reduce the bend torsion coupling seismic response, the approach ...

Abstract: Collective cell motion is crucial for various physiological and pathological processes, and it highly relies on physical factors in cell microenvironment. However, a quantitative understanding of the effect of the physical ...

Abstract: The characteristics of flow instabilities as well as the cavitation phenomenon in a centrifugal pump operating at low flow rates were studied by experimental and numerical means, respectively. Specially, a threedimensional ...
