Title: EXPERIMENT STUDY AND FINITE ELEMENT ANALYSIS FOR CONTAINERLESS PROCESSING BY ACOUSTIC LEVITATION
Abstract:A single-axis acoustic levitator was developed, which can levitate steel ball with density of 7.9 g/cm~ 3 stably. Different reflectors are selected to study the levitation performance in experiment. N...A single-axis acoustic levitator was developed, which can levitate steel ball with density of 7.9 g/cm~ 3 stably. Different reflectors are selected to study the levitation performance in experiment. Numerical calculation and simulation of acoustic field using finite element method (FEM) are performed and the phenomenon that the sample moved along the concave surface of the reflector was analyzed. The result indicates that numerical analysis can interpret the physical phenomenon of acoustic levitation. It is helpful to study more about containerless processing of advanced material and stability of acoustic levitation.Read More
