Experimental and numerical investigations of the performance of fume cupboards
AbstractThe paper stresses the wide use of fume cupboards in different fields of industry, in research laboratories and in teaching institutions. The fume cupboards protect people outside the cupboard from hazards of experiments carried out inside.It is often assumed that protection exists when a sufficiently strong air stream is maintained from the laboratory through the fume cupboard to the exhaust air system. However, it is shown that this assumption is only valid for a few specially designed cupboards. For many cupboards in use it does not necessarily apply, even when the sash opening is nearly closed.An experimental test facility which was set up to test the performance of fume cupboards is described. Test results are given indicating the protection that the cupboard can provide for various front window openings.Numerical investigations of the flow inside the cupboard are described. These were carried out to yield explanations for the experimentally obtained results. The computer programs used also permit optimization of the flow inside fume cupboards and are suggested for use in future developments.
