The technical presentation compared two acoustics software packages, namely COMSOL Multiphysics®, a commercial software and NGSolve, an open-source general-purpose finite element library to accurately resolve the acoustic field of FT wind sensors and showcase part of the numerical capabilities developed at FT Technologies and physical comprehension underpinning our Acu-Res® Technology. FT Technologies relies on high-fidelity numerical models and on the accuracy of numerical methods to address the complexity of sensor acoustics and aerodynamics within the realm of ultrasonic frequencies, turbulent flow, and high velocities. Hence, it is essential to develop numerical methods that can be integrated into our research and design lifecycle of wind sensors to address the needs of FT’s customers.

Speaking after the conference, Dr Jimenez-Garcia said:

“Presenting at the 54th Spanish Congress on Acoustics and showcasing part of our acoustics capabilities was truly fantastic. Engaging in technical discussions with field experts and esteemed researchers regarding industry best practices and state-of-the-art acoustics research was very enriching. In this work, we demonstrated the capabilities to accurately resolve the acoustics field of FT wind sensor within a few minutes using high-fidelity numerical models. The capability to numerically simulate the physics of the interaction of acoustic and aerodynamic fields and the geometry enables us to improve our current designs and iterate over future sensor designs.”
