DYNAMIC FLUID MACHINE WITH EXPONENTIAL INLET

An inlet includes a nozzle inlet for receiving fluid flow, a nozzle outlet for supplying fluid flow, and an exponential cross-sectional profile configured to control fluid flow to provide a highly uniform flow distribution at the nozzle outlet. The exponential cross-sectional profile of the inlet is defined by a nozzle inlet radius, a nozzle exit radius, a nozzle length, an axial coordinate defined with respect to the nozzle inlet, and an exponential shape constant α. The inlet can be included with a dynamic compressor that has an impeller that receives fluid flow from the inlet and dispenses high velocity fluid flow, a diffuser that receives high velocity fluid flow from the impeller and converts the high velocity fluid flow into a high pressure fluid flow, and a discharge collector that receives the high pressure fluid flow from the diffuser and discharges the high pressure fluid flow from the dynamic compressor.
