Claim 37:
38. A fluid flow device, comprising:
a conduit;
a variable aperture, situated within the conduit, through which a fluid flows in a fluid flow direction from an upstream portion of the conduit, which is upstream of the variable aperture relative to the fluid flow direction, to a downstream portion of the conduit, which is downstream of the variable aperture relative to the fluid flow direction;
an actuator that provides motion to adjust dimensions of the aperture;
a first pressure sensor configured to measure a first pressure at a first location in the upstream portion of the conduit; and
a second pressure sensor configured to measure a second pressure at a second location in the downstream portion of the conduit, wherein the second location is determined to be within a stagnation zone that arises in a wake of the variable aperture.
