Mitigating the sound of a flapping airfoil using optimal structural properties distributions
Autor: Eran Arad, Michael Weidenfeld
Publikováno v: Journal of Sound and Vibration. 432:235-248
We study the effects of structural properties distributions on the sound radiation of a thin elastic airfoil. Focusing on flapping-flight in a high-Reynolds and low-Mach regime, we seek optimal conditions to mitigate flapping-sound while maintaining

The evolution of local instability regions in turbulent non-premixed flames
Autor: Yuval Dagan, Eran Arad, Y. Tambour
Publikováno v: Journal of Fluid Mechanics. 803:18-50
Unsteady turbulent flame evolution in non-premixed combustion has been computationally investigated using large eddy simulations. A simple coaxial combustion chamber, subjected to highly unsteady, turbulent recirculating flow is considered, following

Drag-Reduction Mechanisms of Suction-and-Oscillatory-Blowing Flow Control
Autor: Tom Shtendel, Eran Arad, Jacob Wilson, David Schatzman, Avraham Seifert
Publikováno v: AIAA Journal. 52:2491-2505
An active-flow-control study, using steady suction-and-oscillatory-blowing actuators, was conducted on an axisymmetric bluff-body model for a range of Reynolds numbers between 2×106 and 5×106. Prev...

Flow Response of Active Flow Control Actuators
Autor: Jacob Wilson, Manikandan Ramasamy, Eran Arad
Publikováno v: AIAA Journal. 52:998-1009
Numerical and experimental analysis of a synthetic jet actuator in quiescent air is reported. The study focuses on the actuator itself and on the vorticity field as well as on structures that are generated by the actuator. Large eddies simulation was

Analysis of Shroud Release Applied for High-Velocity Missiles
Autor: Yuval Dagan, Eran Arad
Publikováno v: Journal of Spacecraft and Rockets. 51:57-65
A detachable missile nose was designed, tested, and implemented in a new missile. This design enables the use of low-drag supersonic configurations for the major part of the flight, with the application of blunt seekers that are active during the end
