Description

ÉTUDIANT 19 : Teotia Vaibhav
The present internship aims to investigate the impact of atmospheric absorption and turbulence on sound propagation in the Martian atmosphere using three-dimensional numerical simulations of the parabolic approximation of the wave equation. The study will examine the attenuation of acoustic waves due to vibrational relaxation in CO2 and the effects of temperature fluctuations and turbulence on wave scattering. Furthermore, a comparative analysis between Mars and Earth will highlight key differences in acoustic propagation due to variations in atmospheric composition and dynamics.
