A STUDY OF FLUID FLOW THROUGH FLEXIBLE ORIFICES
Abstract
The problem considered in this work was to develop a method for determining mass flow rates of water through a given type of flexible orifice as a function of pressure drop. The theoretical development was for rubber orifices having cylindrical holes and supported by flat back up plates having circular openings. This work was done as an introduction to the general problem of designing a flexible orifice which would produce a desired mass flow rate pressure difference relation.Experimentation done in trying to develop a flexible orifice which would have a constant mass flow-rate over a wide range of pressure drops yielded a large variety of flow-rate versus pressure drop relations. These curves varied from steeper than a solid orifice relation to cases where the flow-rate reached a maximum and then decreased to zero as the pressure increased. These various relations led to this investigation.
