This paper presents the methodology for spatial modeling of thermal discharge into water systems, including calculations of velocity field evolution, pressure and temperature fields for liquid media, and processes of heat-mass exchange at the interfacial area. The methodology of stable calculation for complicated shape of calculated domain on a base of artificial viscosity was applied. Test experiments are discussed for nonstationary three-dimensional modeling of human-induced thermal discharge in both flowing and static water systems. Described methodology is useful for environmental impact assessment of waste heat discharge from power plant cooling systems into water basin.
Key words: water systems, temperature fields, thermal discharge, spatial modeling, meteorological data
