Numerical simulation of gasdynamic processes and the dynamics of dust particles in catastrophic volcanic explosions by applying TVD schemes

We developed a physicomathematical model to predict volcanic explosion-induced gasdynamic phenomena and the dynamics of the distribution of particles of ash and dust that precipitate onto the earth's surface and that remain in the atmotsphere. We investigated the factors and processes that exer...

Description
Summary:We developed a physicomathematical model to predict volcanic explosion-induced gasdynamic phenomena and the dynamics of the distribution of particles of ash and dust that precipitate onto the earth's surface and that remain in the atmotsphere. We investigated the factors and processes that exert an influence on the transport of dust particles in the atmosphere. On the basis of the physicomathematical model developed, numerical simulation of volcanic explosions of specified power and space scale is done, and results on the dynamics of gasdynamic flows of air and the distribution of dust particles for different instants of time are analyzed.[PUBLICATION ABSTRACT]
