This study is a part of a research project named 'Convective Flows and Vertical Temperature Gradient within Active Displacement Air Distribution'. The project was started in 1996 in order to determine guidelines for air flow rate dimensioning of the system. Aim of this study was to determine the characteristics of the thermal plumes of the heat sources used in the project. The characteristics were determined in order to apply the results to different kinds of plumes, which may occur with active displacement air distribution system. The focus was to determine the conditions where the plumes are able to penetrate the active displacement air flow pattern. Two other papers named Convective Flows and Vertical Temperature Gradient with the Active Displacement Air Distribution and Test Room and Measurement System for Active Displacement Air Distribution regarding this study are also submitted to be presented at this conference.
