Turbulent model validations with CFD/wind tunnel test and application to SEA for wind noise prediction

Autor: Kai Aizawa, Steve Sorenson, Hidenori Morita, Richard DeJong, Masashi Komada, Susumu Terakado

Publikováno v: INTER-NOISE and NOISE-CON Congress and Conference Proceedings. 263:175-186

Wind noise is becoming to have a higher priority in automotive industry. Several past studies investigated whether SEA can be utilized to predict wind noise by applying a turbulent spectrum model as the input. However, there are many kinds of turbule

Structural health monitoring of wind turbine blades using acoustic microphone array

Autor: Christopher Niezrecki, Gunnar Heilmann, Peyman Poozesh, Javad Baqersad, Kai Aizawa, Murat Inalpolat

Publikováno v: Structural Health Monitoring. 16:471-485

This article proposes a non-contacting measurement technique based on acoustic monitoring to detect cracks or damage within a structure by observing sound radiation using a single microphone or a beamforming array. The technique works by mounting an

An acoustic-array based structural health monitoring technique for wind turbine blades

Autor: Murat Inalpolat, Peyman Poozesh, Christopher Niezrecki, Kai Aizawa, Gunnar Heilmann, Javad Baqersad

Publikováno v: SPIE Proceedings.

This paper proposes a non-contact measurement technique for health monitoring of wind turbine blades using acoustic beamforming techniques. The technique works by mounting an audio speaker inside a wind turbine blade and observing the sound radiated

Shock Response Fixture Developed from Analytical and Experimental Data and Customized Using Structural Dynamics Modification Techniques

Autor: Kai Aizawa, Peter Avitabile

Publikováno v: Special Topics in Structural Dynamics, Volume 6 ISBN: 9783319047287

In order to characterize the acceleration response of a structure due to shock environments, the Shock Response Spectrum method is widely used in the qualification process for the spacecraft industry. Generally, this test is performed with a shock te

Wind turbine blade health monitoring using acoustic beamforming techniques

Autor: Kai Aizawa, Peyman Poozesh, Gunnar Heilmann, Christopher Niezrecki

Publikováno v: The Journal of the Acoustical Society of America. 135:2392-2393

Wind turbines operate autonomously and can possess reliability issues attributed to manufacturing defects, fatigue failure, or extreme weather events. In particular, wind turbine blades can suffer from leading and trailing edge splits, holes, or crac
