ABSTRACT Zhang & Faghri University of Rhode Island CTS-9422629 Experiments and computer simulations will be conducted to study the effects of vibration on phase change and sedimentation. Of particular interest is determining if the heat transfer rate can be enhanced or diminished under a wide range of physical parameters and by the selection and control of the Vibration frequencies and amplitude. Three types of materials will be investigated: Those having a solid/liquid density ratio less than, equal to and greater than one. If the heat transfer rate can be modified by vibration, potential applications exist in, for example, materials processing, metallurgy, crystal growth, and casting.

摘要张法里，美国罗得岛大学，CTS-9422629 实验和计算机模拟将进行研究振动的相变和沉降的影响。 特别令人感兴趣的是确定在宽范围的物理参数下以及通过选择和控制振动频率和振幅是否可以增强或减小传热速率。 将研究三种类型的材料：那些具有固体/液体密度比小于，等于和大于1。 如果热传递速率可以通过振动来改变，则存在潜在的应用，例如，材料处理、冶金、晶体生长和铸造。
