Abstract: To identify sound sources situated in a fluid flow, an equivalent source method (ESM)-based nearfield acoustic holography (NAH) in a moving medium is proposed, and two types of acoustic inputs, pressure and particle velocity, ...

Abstract: An inverse direct time domain boundary element method (IDTBEM) is proposed for the reconstruction of transient acoustic field radiated by arbitrarily shaped sources. The method is based on the theory of direct time domain ...

Abstract: This paper provides a non-contact approach to reconstruct the distributed or concentrated force applied to a plate in the time domain. This approach is based on sound pressure measurements and is realized by coupling the ...

Abstract: In response to the issue of foundation ring and concrete cracking in operational wind turbine foundations, this study proposes a novel method for health monitoring and damage assessment of foundation structures utilizing ...
