Dynamic behavior of panel radiators - thermographic investigation and computer modeling of heat-up

Research project dealing with dynamic behavior of panel radiators is motivated by current needs for energy savings. Radiators of various types and dimensions were experimentally investigated with thermal imaging; obtained data were used in computer models describing heat-up and cool-down of a radiator. In this article, thermographic observation of fluid flow in a radiator as well as several strategies of heat-up modeling are described and discussed.
