Nonlocal turbulent transport in a buoyant vortex ring during the ascent of a thermal in a stratified atmosphere
The flow initiated by a hot gas cloud (thermal) in a stratified atmosphere is calculated on the basis of theκ-ε turbulence model and the transport model for the Reynolds stresses and turbulent fluxes and the resu...

Motion of gas due to a point explosion in an inhomogeneous atmosphere
The problem of a strong point explosion in an atmosphere with exponential dependence of the density on the altitude was considered in detail in the monograph [1]. As the blast wave becomes weaker, it is necess...
