Skoltech has presented an innovative approach that allows the use of high-performance parallel computing systems for accurate modeling of chaotic sound wave propagation. This was reported in the press service of the university.
Unraveling the nature of turbulence is one of the most important unsolved problems in physics. We plan to explore other wave systems, for example, large-amplitude ocean waves.
Scientists have found a numerical solution to the equation describing the propagation of sound waves in turbulent conditions. Previously, such data could only be obtained using supercomputers. The new method allows for more accurate calculations using ordinary personal computers.
Experts investigated the propagation of sound waves in a nonlinear medium, similar to liquid superfluid helium at a temperature of about -270°C. Under such conditions, the gas becomes a quantum liquid, and sound waves can propagate chaotically. The calculation results coincided with observational data.
The development opens up opportunities for modeling processes in the ionospheres of stars and giant planets. Simplifying calculations also frees up supercomputer resources for other tasks.
Earlier, www1.ru reported that acoustic sensors were improved in Perm.
