Abstract

Flow and thermal characteristics of warm plane air jets (measurements and predictions using different k-e models) T. Tomstrom^'3, S. Amiif\ B. Moshfegh" 'Department of Energy Technology, SP Swedish National Testing and Research Institute, Boras, Sweden 2 Division of Energy and Mechanical Engineering, Department of Technology, University of Gdvle, Gdvle, Sweden Division of Energy Systems, Department of Mechanical Engineering, Linkoping Institute of Technology, Linkoping, Sweden Tekniska Verken i Linkoping, Linkoping, Sweden Abstract Jets are often used for supplying air to buildings. For designing ventilation systems it is therefore of great importance to have a good understanding of air jets to avoid draught, which might lead to discomfort. At the same time as we want a good indoor climate, we also want to reduce energy consumption. The purpose of this study is to investigate the flow and thermal characteristics of warm air jets supplied under the ceiling, as a heati
