Tricolor Technique for Visualization of Spatial Variations of Polydisperse Dust in Gas-Dust Flows
Vitaly V. Korolev, Mikhail A. Bezborodov, Ilya G. Kovalenko +2
The aim of this work is to construct an algorithm for visualizing a polydisperse phase of solid particles (dust) in an inhomogeneous flow of a two-phase gas-dust mixture that would…
On the possibility of laboratory simulation of quasi-spherical accretion onto black holes with a shallow-water experimental setup
A. V. Semyannikov, I. G. Kovalenko
We describe the concept of a shallow-water setup for simulation of gas accretion onto a black hole in the mode of a quasi-spherical accretion. The bottom for the shallow-water cont…
Coherence loss in stroboscopic radar ranging in the problem of asteroid size estimation
V. D. Zakharchenko, I. G. Kovalenko, V. Yu. Rizhkov
We consider the problem of coherence loss in a stroboscopic high resolution radar ranging due to phase instability of the probing and reference radio signals. Requirements to the c…
Resonant Amplification of Turbulence by the Blast Wawes
A. M. Zankovich, I. G. Kovalenko
We discuss an idea whether spherical blast waves can amplify by a non-local resonant hydrodynamic mechanism inhomogeneities formed by turbulence or phase segregation in the interst…
Dynamics of a Supernova Envelope in a Cloudy Interstellar Medium
V. V. Korolev, E. O. Vasiliev, I. G. Kovalenko +1
The evolution of a supernova remnant in a cloudy medium as a function of the volume filling factor of the clouds is studied in a three-dimensional axially symmetrical model. The mo…
Estimate of sizes of small asteroids (cosmic bodies) by the method of stroboscopic radiolocation
V. D. Zakharchenko, I. G. Kovalenko, O. V. Pak
Radiolocation methods of probing minor celestial bodies (asteroids) by the nanosecond pulses can be used for monitoring of near-Earth space with the purpose of identification of ha…
On Protecting the Planet Against Cosmic Attack: Ultrafast Real-Time Estimate of the Asteroid's Radial Velocity
V. D. Zakharchenko, I. G. Kovalenko
A new method for the line-of-sight velocity estimation of a high-speed near-Earth object (asteroid, meteorite) is suggested. The method is based on use of fractional, one-half orde…
Wavelength limits on isobaricity of perturbations in a thermally unstable radiatively cooling medium
I. G. Kovalenko, Yu. A. Shchekinov
Nonlinear evolution of one-dimensional planar perturbations in an optically thin radiatively cooling medium in the long-wavelength limit is studied numerically. The accepted coolin…
