Abstract

The temperature-dependent physical conditions for single-axis acoustic levitation were analyzed considering the deviation of the actual acoustic field from the plane standing wave approximation. The effects of temperature variation on the resonant conditions, levitation force and threshold pressures p_m and p_M were discussed by assuming a quasi-static heating and cooling process. The results showed that for the containerless processing of water and the Pb-Sn eutectic alloy, p_m decreases whereas p_M increases with the enhancement of temperature.
