The Vavilov-Cherenkov radiation in Abraham's theory

Sergey G. Chefranov

It is shown that the threshold of the observed Vavilov-Cherenkov radiation is more accurately described by the new quantum theory, based on the theory of Abraham (1909), compared w…

Linear instability of plane Couette and Poiseuille flows

Sergey G. Chefranov, Alexander G. Chefranov

It is shown that linear instability of plane Couette flow can take place even at finite Reynolds numbers which meets with known experimental data. This new result of the linear the…

Revision of the linear stability paradox for known bounded shear flows

Sergey G. Chefranov, Alexander G. Chefranov

The well-known paradox of linear stability for the some bounded shear flows is not solved up to now and is bypassed on the basis of the non-linear mechanisms consideration. We prov…

Investigating the dynamics of point helical vortices on a rotating sphere to model tropical cyclones

Sergey G. Cherfanov, Igor I. Mokhov, Alexander G. Chefranov

A general exact weak solution to the nonlinear equation of the conservation of the absolute vorticity in a thin layer of an incompressible medium on a rotating sphere is proposed.…

The cylindrical shock at underwater wire explosion

Sergey G. Chefranov, Daniel Maler

New analytical solution of the piston and shock evolution for the wire electrical explosion in water is obtained. This is provided on the base of the compressible Euler equations w…

Equation of state based on the first principles

Sergey G. Chefranov

An alternative to the well-known complete form of the Mie-Grüneisen equation of state (EOS) for water is suggested. A closed analytical description of the self-consistent EOS for a…
