Abstract

Total radiation force on a spherical levitating object, which is placed between a single axis acoustic levitator, is obtained using finite element simulation. Variation in the total radiation force on the spherical levitating object with respect to the position of the object between the driver and the reflector is studied in resonance as well as non-resonance condition. Simulation results are verified with experimental results available in the literature. Further, a parametric study has been performed on the radius of curvature of driver and reflector. Three different cases have been considered. (1) Curved driver surface with flat reflector surface. (2) Curved reflector surface with flat driver surface. (3) Both driver and reflector having curved surfaces. It is observed that the case with both driver and reflector surfaces being curved results in maximum radiation force on the spherical levitating object. The values of radius of curvature for maximum radiation force for all three cases are also obtained. Total radiation forces for all three cases (with optimum value of radius of curvature) as well as the flat surfaced driver-reflector arrangement are compared.

单轴声悬浮器驱动器和反射器的有限元分析

摘要

使用有限元模拟获得放置在单轴声悬浮器之间的球形悬浮物体上的总辐射力。在共振和非共振条件下,研究了球形悬浮物体上的总辐射力相对于物体在驱动器和反射镜之间的位置的变化。仿真结果通过文献中提供的实验结果进行了验证。此外,已经对驱动器和反射器的曲率半径进行了参数研究。已经考虑了三种不同的情况。(1)弯曲的驱动器表面,反射器表面平坦。(2)弯曲的反射器表面带有平坦的驱动器表面。(3)驱动器和反射器均具有弯曲的表面。观察到驱动器和反射器表面都弯曲的情况导致在球形悬浮物体上的最大辐射力。还获得了所有三种情况下最大辐射力的曲率半径值。比较了所有三种情况下的总辐射力(具有最佳曲率半径)以及平坦的驱动器-反射器装置。
