## About the Department

Department was opened in 1865. Professor Sokolov Ivan Dmitriyevich, rector of the Novorossiysk University, was the first head of the department. Doctor of Physics and Mathematics, professor Aslanov Sergey Kostantinovich has been managing the department since 1964.

Department includes the research laboratory for mechanics and the computational laboratory.

## Scientific activities

The department has its own scientific school: the school of gas dynamics and theory of combustion and explosion.

The directions of scientific studies of the department:

- Theory of hydrodynamic stability.
- The dynamics of fast processes in inert and chemically active environments.
- Dynamics of aerosols formation.
- Self-organization of nonequilibrium systems structure.

Today the following research projects are under development:

- Theme № 179 “Application of parallel computing to the numerical modeling problem of detonative and explosive waves spreading in three-dimensional space” (Research supervisor Professor S. K. Aslanov).
- Theme № 203 “Research of rotatory motions of satellite relative to the center of mass influenced by disturbing moments” (Research supervisor Professor S. K. Aslanov).

**Primary results of the department fundamental studies**

- It was built analytical theory of shockwaves, which spread from different explosive substances. It was built the theory of the collapse of fluidic streams from the perspective of the hydrodynamic instability.
- The theory of aerosol system detonation was built.
- The theory of destruction of meteoritic bodies penetrating into the atmosphere was built.
