【 摘 要 】

A boundary-element method (BEM) is used to compute axisymmetric acoustic fields inthe gap between the radiating plate and reflector of a single-axis acoustic drop levitator, inorder to better understand the dependence of levitation capability on geometric parameters.Modifications to the drop levitator radiating plate are investigated using the BEM. Gor’kov’stheory is used to calculate the acoustic forces acting on a drop in the levitation field. Thelevitation capability of a modified geometry is compared to that of a current experimentalgeometry. Indenting, and increasing the area of the radiating plate significantly enhanceslevitation capability.
