An inducer (140) that includes a profiled throat (144). In some embodiments, the inducer (140) includes a conical shape upstream of the profiled throat (144) with a relatively large circular inlet (142) that narrows to the profiled throat (144) and, downstream of the profiled throat (144), a downstream section that broadens from the profiled throat (144). The profiled throat (144) may include an approximate convergent-divergent nozzle geometry.
