Control of Reynolds number in a high speed wind tunnel
(Departamento de Ciência e Tecnologia Aeroespacial, 2009)
A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel ...
Piezoceramic Composite Actuators for Flow Control in Low Reynolds Number Airflow
(SAGE PUBLICATIONS LTD, 2010)
The research presented here employs solid-state actuators for flow separation delay or for forced attachment of separated flow seen in airfoils at low Reynolds numbers. To reduce separation, periodic excitation to the flow ...

Transition to turbulence in the Reynolds' experiment
(Elsevier B.V., 2001-08-01)
In this study we simulate numerically the Reynolds' experiment for the transition from laminar to turbulent flow in a pipe. We present a discussion of the results from a dynamical systems perspective when a control parameter, ...

Macro-Fiber Composite Actuators for Flow Control of a Variable Camber Airfoil
(SAGE PUBLICATIONS LTD, 2011)
This research employs solid-state actuators for delay of flow separation seen in airfoils at low Reynolds numbers. The flow control technique investigated here is aimed for a variable camber airfoil that employs two active ...
URANS calculations for smooth circular cylinder flow in a wide range of Reynolds Numbers: solution verification and validation
(ASMENew York, 2013-08-02)
The flow around circular smooth fixed cylinder in a large range of Reynolds numbers is considered in this paper. In order to investigate this canonical case, we perform CFD calculations and apply verification & validation ...
