Maximum Thickness Location Selection of High Subsonic Axial Compressor Airfoils and Its Effect on Aerodynamic Performance

Frontiers in Energy Research, 2021
Solidity and camber angle are key parameters with a primary effect on airfoil diffusion. Maximum thickness location has a considerable impact on blade loading distribution. This paper investigates correlations of maximum thickness location, solidity, and

Factors in perioperative care that determine blood loss in liver surgery [PDF]

, 2012
Excessive blood loss during liver surgery contributes to postoperative morbidity and mortality and the minimizing of blood loss improves outcomes. This study examines pre- and intraoperative factors contributing to blood loss and identifies areas for ...

Control of Corner Separation in Compressor Cascade Using Biomimetic Fish Scales Structure

Biomimetics
In this study, a fish scale structure with low viscous drag was proposed and applied to the suction surface of a compressor cascade to reduce total pressure loss and suppress corner separation, a key source of compressor inefficiency.

Grounding and the influence of the total pressure losses in ducted wind turbines

Wind Energy, 2009
AbstractDucted wind turbines are known to exceed the Betz limit for the power that may be extracted from free currents per unit cross‐sectional area of their rotors. The present study points to another advantage: the fact that the turbine rotor (and the associated subassemblies) need not be lifted up on the air and rotated to align with the wind.

Fish Scale-Inspired Flow Control for Corner Vortex Suppression in Compressor Cascades

Biomimetics
Corner separation at the junction of blade surfaces and end walls remains a significant challenge in compressor cascade performance. This study proposes a passive flow control strategy inspired by the geometric arrangement of biological fish scales to ...

GGOT total pressure loss control concept evaluation [PDF]

, 1993
Total pressure loss is one of the most important parameters in the design of a turbine. This parameter effects not only the turbine performance, but consequently the engine power balance and engine performance.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Comprehensive Controlling Study of Blade Groove-induced Jets on Three-dimensional Corner Separation and Mid-span Trailing Edge Separation [PDF]

Journal of Applied Fluid Mechanics
Blade groove-induced jets have been shown to effectively control flow separation in compressors. However, the optimal span-wise groove layout for grooved blades still requires further investigation.
