    Acoustic/Fluid Dynamic Phenomena

    Analysis, measurement, and control of subsonic and supersonic flows, vortex-driven flows, reacting and non-reacting flows, combustion instabilities, flow acoustic interactions and resonance, and flow receptivity to acoustic disturbances.

    Active Noise Control
    Alliva control 0f noise and related unsteady flows and vibration; noise cancellation through active acoustic treatment, and active source control as related to noise and vibration in the cabin, and within engine ducts and jets; development of associated sensors and actuators; and feedback and feed-forward control strategies.

    Advanced Testing Techniques
    Development and application of novel testing techniques, advanced diagnostic methods, and test facilities. Topics of particular interest are detailed measurements of mean and turbulent flow phenomena that contribute to noise generation and/or affect the radiated sound; source localization; flow, reverberation, and noise effects on measured data and their suppression; properties of sound-absorbing materials, including bulk absorbers and liners at high temperatures; interior-noise test facilities, includlng source simulation and noise-source path identification; and comparisons of model and full-scale testing.

    Airframe/High-Lift Noise
    Noise source mechanisms of flow/surface interaction as related to airframe acoustics. Measurement, analysis, and prediction methods for wing, flap, slat, and landing gear noise. Noise reduction strategies including devices and methods of circulation and boundary layer control. 

    Community Noise and Metrics
    Response of individuals and the community to aircraft noise, including noise from rotary wings, prop-fans, sonic boom, and subsonic and supersonic jets; noise assessment methodologies and criteria for adaptability; tools for land-use planning with respect to airport noise; development of airport noise reduction strategies and airport noise monitoring methods.

    Computational Aeroacoustics
    Development of innovative numerical techniques for aeroacoustics applications. Emphasis is placed on the ability of algorithms to simulate and/or track accurately acoustic information from flows, and on the development of proper boundary conditions for aeroacoustic applications. Applications are sought in areas of sound generation by turbulence, unsteady flows, or moving boundaries; and propagation, transmission, and scattering of sound through non-uniform flows.

    Duct Acoustics
    New and innovative methods to analyze, predict, and control the turbomachinery noise propagating through nacelle ducts. A topic of particular interest is lightweight passive and active/adaptive liners to control the noise in ducts.

    General Acoustics
    Theoretical, numerical, and experimental research involving all areas of physical acoustics and those involving noise associated with commercial systems.

    Integration Effects and Flight Acoustics
    Aeroacoustics effects of propulsion and airframe integration. Understanding and prediction of noise source modifications originating from the interaction of flow and/or acoustic propagation mechanisms. Noise reduction approaches based on aspects of propulsion and airframe system integration or aircraft configuration. Integrated test model and flight vehicle acoustic experimental and/or prediction research.

    Interior Noise/Structural Acoustics
    Reduction of interior noise and vibration associated with aircraft, Space Shuttle configurations, expendable launch vehicles, and automobiles; noise transmission through structures; structure and payload response; and vibro/acoustic test and prediction methods.

    Jet Aeroacoustics
    Aerodynamics and aeracoustics of jets focusing on identifying and modeling noise production mechanisms; near-field noise; shock noise; turbulence prediction and characterization for subsonic, supersonic, and noncircular and multi-stream jets; and suppression methods for both subsonic and supersonic jet noise. Of psrticular interest are new aeroacoustic modeling methods and flow and noise diagnostics techniques; and the effects of jet heating on the experimental data and on the modeling.

    Loads/Sonic Fatigue
    Prediction, testing, design, and control of sonic fatigue; sources of fluctuating loads on structures; jet/structure interactions; flow resonance phenomena; structural and material stress-strain responses; and high temperature effects.

    Propeller, Rotocraft, and V/STOL Noise
    Conventional and advanced single and counter rotating propellers, tone and broadband noise, propagation and ground reflection effects, fuselage boundary layer refraction and scattering, noise source control, effects of inflow distortions, and installation effects. Rotorcraft source studies, including rotor harmonie noise, highspeed impulsive and blade/vortex interaction noise, blade-turbulence interaction noise, jet/surface interaction noise induding both ground and aircraft surfaces. Components and system noise prediction and validation, ground and flight test measurements, and noise control/reduction strategies.

    Sonic Boom
    Modeling and prediction of noise from Supersonic Business Jets. Methods for sonic
    boom prediction, minimization through design and/or operation, response studies, and metrics; atmospheric affects on noise propagation including refraction, diffraction, absorption, and turbulence scattering.

    Turbomachinery and Core Noise
    Generation, propagation, and control of noise from fans, compressors, combustors, and turbines; propagation and interaction with the mean flowfield; transmission and reflection from blade and vane rows; generation of afterburner noise; control using active or passive techniques; and measurement techniques for source identification.

    Student Paper Award
    Undergraduate and graduate students are encouraged to submit papers for consideration in the Aeroacoustics Student Paper Competition. Student papers should report on thesis work conducted by students in collaboration with faculty advisors. The student submitting a paper for consideration must be the primary author, and must have been a student at the time of the preceding Aeroacoustics Conference. Papers submitted by students must be presented by the primary author at the conference. The student author of the best paper will receive a monetary award and certificate during the conference. The award will be selected on the basis of the technical quality of the paper, including its presentation. Papers not received by the student paper submission deadline or not presented by the student at the conference will not be considered for the award.

    Interested students should select "Student Paper Submission" as the presentation type when submitting their extended abstract and send an email to the Organizing Committee (Iars.enghardt@dlr.de and philip.nickenig@dglr.de) stating that you want your paper to be considered for the student award. Authors participating in the Student Award competition must also send a copy of their manuscript to the Education Subcommittee Chair (s.w.rienstra@tue.nl) no later than 29 April 2013. Please use "Student Paper Manuscript" as the subject line of your e-mail.
