Abstract
An open-source implementation of the Amiet model for turbulence-airfoil interaction noise implemented in Python programming language is presented. The proposed implementation, named amiet_tools, allows the user to calculate the unsteady surface pressure jump and the radiated acoustic pressure due to a single or multiple turbulent gusts interacting with a flat plate airfoil. Secondary effects such as the acoustic near-field, finite-span effects, subcritical gusts contribution, and sound refraction at a planar shear layer are available for simulating a realistic open-jet wind tunnel test setup. Prediction results are presented and compared to measured acoustic pressures obtained in an open-jet wind tunnel with a planar spiral microphone array, and good agreement is obtained over a wide range of frequencies. A link for downloading the package codes and sample experimental data is included. It is expected the proposed implementation can be adopted as a quick benchmark for more advanced analytical airfoil noise models and experimental measurements.
