Abstract L. Glicksman - CTS 9712053 The principal investigator proposes to study the influence of fluidized bed hydrodynamics, particularly the characteristics of the gas layer near the wall and the adjacent clusters of solids and their contact time, on the heat transfer. The emphasis will be on rough walls and tube-fin walls. An understanding of the statistical nature of the contact time is necessary for the future development of models that incorporate radiative transfer between surface adjacent to the dilute gas-solid mixture and the bed core.

摘要 L. Glicksman - CTS 9712053 主要研究者建议研究流化床流体动力学的影响，特别是壁附近的气体层和相邻的固体簇及其接触时间的特性，对传热的影响。 重点将放在粗糙的墙壁和管翅壁。 接触时间的统计性质的理解是必要的，未来的发展模式，将辐射传输表面相邻的稀气固混合物和床芯之间。
