To support experiments scheduled for the First United States Microgravity Laboratory (USML-1) shuttle mission, experimental and computer simulation methods have been developed which allow ground-based investigation of the translational, rotational, and vibrational motions of single and dual liquid drops in an external acoustic field in a microgravity environment. The acoustic fields used are the 3-D orthogonal resonant modes of a rectangular chamber. Hardware and software development are described in detail. Results for the translation of single and dual drops are presented, and semi-automated schemes for controlled translation are proposed, tested, and evaluated.
