Aerothermoelastic-Acoustics Simulation of Flight Vehicles [PDF]
AIAA Journal, 2017 This paper describes a novel computational-fluid-dynamics-based numerical solution procedure for effective simulation of aerothermoacoustics problems with application to aerospace vehicles. A finite element idealization is employed for both fluid and structure domains, which fully accounts for thermal effects.

Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena) [PDF]
, 2015 Funding: Det Frie Forskningsrad (MJ)Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity

Simulation of Surface Acoustic Wave Devices [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004 The Mason crossed-field circuit model is generalized to simulate apodized interdigital transducers without channel division. The apodized transducer model is based on the transmission line model, and the artificial transformer with different voltage and current coupling ratios is used to independently obtain the transfer function and radiation ...

All-pass phase shifting achieved by acoustic unidirectional guided resonances
Applied Physics Express, 2023 Phase manipulation of sound is an important function for many acoustic applications. Here, we apply temporal coupled mode theory to demonstrate that sound all-pass phase shifting, which means that acoustic waves propagate with unit amplitude but have ...

Computer graphics visualization for acoustic simulation [PDF]
ACM SIGGRAPH Computer Graphics, 1989 Computer simulations can be used to generate the spatial and temporal data describing the acoustical behavior of performance halls, but typically the analytical results are difficult to assimilate and compare. By using computer graphics to display the multi-dimensional data, substantially greater amounts of information than that conveyed by standard ...
