Book Description
The flow induced pressure field in a reed valve arrangement was analytically predicted and experimentally measured for steady state conditions. The flow was found to be supersonic in nature with an imbedded shock for all but the lowest pressure runs. The analytic method used one-dimensional isentropic and normal shock relations. The technique provides a good first look at the nature of the flow and is compatible for use on a small computer system. The experimental data was obtained by using an idealized reed valve model. The data acquisition system was computerized and used a scanivalve system to measure the pressure in the valve model. Circular, square, and rectangular valve plate geometries were investigated. The inlet was circular for all cases. Flow visualization oil was also used in a qualitative approach to determine the location and shape of the shock in the flow. The pressure measurements and the flow visualization showed the shock to be circular for all geometries and pressures tested. At high total pressure runs the valve plate began vibrating and the shock location became smeared suggesting the shock was also oscillating. (Thesis).

Book Description
Reed values are spring-metal plates which commonly serve as intake and exhaust valves in compressor units of refrigeration systems. This thesis reports on an analytic and experimental study of flow through reed-valve-like inlet geometries. In these inlet geometries, with reservoir pressures up to 2 1/4 times ambient, the flow passed through a hole in a base plate, stagnated, and turned 90 degrees by a disk centered over the hole, and directed radially outward between the base plate and the disk. Cover-plate-like geometries up to 3 times the diameter of the hole in the base plate, as well as modified base-plate geometries, were investigated. The analytic model used one-dimensional (radially symmetric) compressible flow relations to model the inlet geometries in an initial supersonic region which accounted for friction and possible separation. Shock matching techniques were then employed to locate a shock and predict the properties of the flow just behind the shock. Finally, subsonic, insentropic, compressible equations were used to model the flow from the shock to the exit. The analytic modelling was compared with the experimental results and found to satisfactorily explain the qualitative character of the flows, and to some degree the quantitative nature of the flows. The results of this study suggest that reed-valve inlet geometries should have relatively thin and high-lipped inlet configurations so as to minimize total pressure loss. Furthermore, the study indicates that the cover plate of a reed valve should barely cover the inlet to minimize the likelihood of any severe noise and vibration. (Author).
