SIMPLIFIED STATIC PERFORMANCE CHARACTERISTICS OF LOW-PRESSURE PLENUM AND PERIPHERAL JET FLUID SUSPENSIONS

Simplified relationships and approximate design curves and nomograms are presented which permit the power, mass flow and stiffness of simple plenum and peripheral jet fluid suspensions to be estimated. Both gravity-loaded and transverse suspensions are considered. The incremental load capacity divided by the design load (force increment) is shown to be a major design parameter for fluid suspensions. Compared with simple orifice-restricted plenums, peripheral jet suspensions are shown to require less power and mass flow and to possess lower stiffness for comparable operating conditions. The advantage in power and flow increases as the force increment increases. A comparison is made between the inviscid peripheral jet performance theory used and experimental data which indicates that the theory gives useful estimates of performance which become more accurate as flow Reynolds number increases.
