The Airflow Stagnation Zone Effect of Convective Heat Transfer on Adjacent Indoor Wall
Abstract
The reduction of heat loss through buildings envelopes, i.e. outdoor walls and vertical window areas by means of active control of indoor airflow along adjacent surface areas is described in this work. The aim was to cause air layers adjacent to the room-faced glass surface to slow down their movement and partly divert themselves, so they would form an additional stand-still air area. The convective heat transfer occurring within the laminar as well as turbulent air layer adjacent to inner vertical surface would decrease as showed on a computational 2-dimensional model and experimental data.
