Reduced description method in dynamic theory of particles interacting with medium
We consider spatially inhomogeneous states of particles, weakly interacting with hydrodynamic medium involving Bogolubov’s reduced description method. It has been shown that such a system has both kinetic and hydrodynamic stages of evolution. The coupled system of equations of motion for this evolut...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We consider spatially inhomogeneous states of particles, weakly interacting with hydrodynamic medium involving Bogolubov’s reduced description method. It has been shown that such a system has both kinetic and hydrodynamic stages of evolution. The coupled system of equations of motion for this evolution stage is obtained. The transition from kinetic to hydrodynamic stage of evolution for particles interacting with medium has been also studied. Consequently we obtained a system of equations, which completely describes the evolution of the system on hydrodynamic stage. These equations can describe such systems as neutrons propagating in hydrodynamic medium without multiplication and capture. |
