Ultrasound Flow-Monitoring and Flow-Metering of Air–Oil–Water Three-Layer Pipe Flows

IEEE Access, 2017
The combined use of ultrasound pulse-echo intensity and Doppler shift frequency is examined as a means to measure strong unsteady three-phase pipe flows of a gas and two liquids.

Message Flow Control [PDF]

, 1995
High level communication by means of the exchange of messages between different organizations or organizational units is studied. The concepts of business transaction and business transaction protocol are discussed. Message exchanges are controlled by a message handler that enforces a transaction protocol.

Comparative Study of Dynamic Stall between an Aircraft Airfoil and a Wind Turbine Airfoil in an Air–Particle Flow

Applied Sciences, 2021
Dynamic stall in clean air flow has been well studied, but its exploration in air–particle (air–raindrop or air–sand) flow is still lacking. The aerodynamic performance loss of aircraft (NACA0012) and wind turbine (S809) airfoils and their differences ...

Large-Eddy Simulation of Flow Separation and Control on a Wall-Mounted Hump [PDF]

, 2009
Active flow control techniques such as synthetic jets have been successful in increasing the performance of naturally separating flows on post-stall airfoils, bluff body shedding, and internal flows such as wide-angle diffusers.

Influence of Flow-induced Vibration of a D-VAWT With and Without Leading-edge Rod at Various Pitch Angles [PDF]

Journal of Applied Fluid Mechanics
Under specific incoming wind speeds, Darrieus- Vertical Axis Wind Turbines (D-VAWT) have been found to display significant amplitude vibrations. Previous studies mainly examined the D-VAWT's aerodynamics, ignoring flow-induced vibration (FIV).

Marking function of Stokes number on airfoils’ aerodynamic penalties in a gas–solid flow

IET Renewable Power Generation, 2021
This paper aims to employ the Stokes number to mark aerodynamic penalties of airfoils caused by particles, which is crucial to implement their scaling experiments in a gas‐solid flow.
