RISChallenges in Validating a Thermo-Hydrodynamic Gas Foil Bearing Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas foil bearings (GFBs) are suitable for high speed and temperature applications where conventional lubricated bearing solution are not feasible. This requires the prediction of bearing temperatures and thus a thermal ...
Numerical Investigation of an Elastomer-Piezo-Adaptive Blade for Active Flow Control of a Nonsteady Flow Field Using Fluid–Structure Interaction Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to prevent critical effects due to pulsed detonation propulsion, e.g., incidence fluctuations, an elastomer-piezo-adaptive stator blade with a deformable front part is developed. Numerical investigations with ...
Active Flow Control Utilizing an Adaptive Blade Geometry and an Extremum Seeking Algorithm at Periodically Transient Boundary Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a consequence of constant volume combustion in gas turbines, pressure waves propagating upstream the main flow into the compressor system are generated leading to incidence variations. Numerical and experimental ...
A Physically Consistent Reduced Order Model for Plasma Aeroelastic Control on Compressor Blades
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Plasma actuators may be successfully employed as virtual control surfaces, located at the trailing edge (TE) of blades, both on the pressure and on the suction side, to control the aeroelastic response of a compressor ...
