Abstract
The process of volume annihilation of particles and antiparticles in the gravitational self-field is considered. The problem of homogeneous compression of such a system is solved both within the framework of the general relativity theory and in Newtonian mechanics. Two models of collapsing matter are considered, namely, hot and cold dust filled with radiation. The radiation pressure gradient is taken into account.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
