In spite of the wide application of fluidization techniques in many industrial processes, the design and scale-up of a commercial size fluidized bed reactor is still based on past experience and information obtained from building a sequence of prototype reactors. This procedure is not only costly and time-consuming but has led to overdesigning and delaying of the development of many processes. One of the many problems encountered is the stability of operation. It is in this area that analytical and experimental research will be performed focusing on stabilization against bubbles, electromechanical coupling, and wave propagation and reflection in fluidized beds of dielectric or magnetic particles using electric or magnetic fields.

尽管流化技术在许多工业过程中得到广泛应用，但商业规模流化床反应器的设计和放大仍然基于过去的经验和从建造一系列原型反应器中获得的信息。这一过程不仅成本高昂且耗时，而且导致了许多流程的过度设计和开发延迟。 遇到的众多问题之一就是运行的稳定性。 正是在这一领域，将进行分析和实验研究，重点是使用电场或磁场的介电或磁性颗粒流化床中的气泡稳定性、机电耦合以及波传播和反射。
