Recovery of Boundary Functions on External and Internal Open Boundaries in an Open Sea Hydrodynamic Problem

Autor: V. I. Agoshkov, Tatiana O. Sheloput, N. R. Lezina

Publikováno v: Computational Mathematics and Mathematical Physics. 60:1855-1871

The inverse problem of recovering boundary functions on external and internal open boundaries for an open sea hydrodynamic model based on the linearized shallow water equations is considered. The external open boundary is meant as the boundary separa

Reconstruction of a passive tracer boundary source in an open water area

Autor: Tatiana O. Sheloput, Alexander S. Sorokin

Publikováno v: Ecologica Montenegrina. 25:55-62

Marine pollution is one of the most serious environmental problems nowadays. Identification of sources of contaminants is among the main objectives of environmental researchers. In such problems pollutants are sometimes considered as passive tracers.

The study and numerical solution of some inverse problems in simulation of hydrophysical fields in water areas with ‘liquid’ boundaries

Autor: Tatiana O. Sheloput, Valery Agoshkov

Publikováno v: Russian Journal of Numerical Analysis and Mathematical Modelling. 32:147-164

Some inverse problems related to mathematical modelling of hydrophysical fields in water areas (seas and oceans) under the presence of ‘liquid’ (open) boundaries are studied and solved numerically in the paper. Numerical solution algorithms for t

The study and numerical solution of the problem of heat and salinity transfer assuming ‘liquid’ boundaries

Autor: Valery Agoshkov, Tatiana O. Sheloput

Publikováno v: Russian Journal of Numerical Analysis and Mathematical Modelling. 31

The problem of simulation of physical processes in water areas with ‘liquid’ boundaries is well known in geophysical hydrodynamics. In this paper we consider a problem of heat and salinity propagation as an example of approaches solving such prob
