1. An apparatus (10) for aiding the flow of a liquid (12) in a cavity (14) to improve the filling thereof, comprising:

  • means (18) for generating a plurality of waves (20) in the liquid (12) in the cavity (14) at a first location (50);

    means (38) for sensing the waves (20) at a second location (48) spaced from the first location (50), said first location (48) of said cavity (14) defining a first cross-section generally orthogonal to flow thereat and said second location (50) of said cavity (14) defining a second cross-section generally orthogonal to flow thereat, a minimum dimension of said first cross-section being significantly smaller than a minimum dimension of said second cross-section; and

    means (56) for controlling said generating means (18) in response to the waves (20) sensed by said sensing means (38).
