Abstract
In improvements to the Fluid Energy Pulse Test System, apparatus and methods regulate high-pressure, high-fluid-flow-rate energy pulses to generate temperature-controlled transient, ramp, constant-steady-state, and periodic-steady-state fluid-pressure and fluid-flow-rate test data and sound data for evaluating fluid control devices. Transient, ramp, and constant-steady-state performance curves describe dynamic operating characteristics of tested devices. Transient and constant-steady-state pressures and flow rates are precisely defined and compared. Constant fluid conductance is represented by transverse lines on performance graphs. Constant- and periodic-steady-state pressures and flow rates are achieved in less than two seconds. Temperature sensitivity of fluid control devices is determined. Fluid-pressure and fluid-flow-rate data correlated with sound data create audio-visual representations. Three-dimensional amplitude-frequency-time sound signatures are displayed graphically.
