Summary on Grant Application Form |

Laboratory experiments in water tanks will be undertaken in order to simulate the flow of air within naturally ventilated buildings. These experiments will focus upon time-dependent effects associated with variations in the strength and location of internal and solar gains and the associated coupling effect between the buildings thermal mass and the movement of air within the building. For the latter an innovative experimental approach is proposed in which heat, rather than salinity, is used to produce buoyancy forces. This technique will be carefully tested and an experimental investigation of a set of generic, stack-driven, displacement flows will then be conducted. To begin with the case of an insulating fabric will be considered and this work will then be extended to consider the effects on non-insulating boundaries. Sophisticated flow visualization, measurement and digital image-processing techniques will be used to obtain accurate measurements of thermal stratification and velocity. The development of theoretical models to include the flow features identified in these experiments will continue with parallel with the laboratory work. Through liaison with our industrial contacts at the Building Research Establishment, these results will be applied to improve the design and operation of naturally ventilated buildings.
