Effects on Vibration on Phase Convection and Sedimentation

摘要为了研究振动对相变和沉积的影响，将进行罗德岛大学张和法格里大学CTS-9422629实验和计算机模拟。特别令人感兴趣的是确定在很大范围的物理参数下，通过选择和控制振动频率和幅度，是否可以增强或减小传热率。将研究三种类型的材料：固/液密度比小于、等于和大于1的材料。如果热传递速率可以通过振动来改变，那么它在材料加工、冶金、晶体生长和铸造等方面就有潜在的应用前景。

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.
