Tests with ambient air flow through a nominal 300 mm chamber diameter vortex amplifier demonstrate independence of Reynolds number over the test range. This permits data transformations based on constancy of Euler number at any working point. Data taken with constant control-to-outlet pressure drop are shown to produce characteristics for constant supply-to-outlet pressure drop which would be experimentally discontinuous. The independence of Reynolds number also suggests that pressure losses within the vortex chamber are relatively minor.
