초록

The commercial viability of heat exchanger is mainly dependent on their long-term fouling characteristics because the feeling increases the pressure loss and degrades the thermal performance of a heat exchanger An experimental study was performed to investigate the characteristics of fluid flow in a fluidized bed heat exchanger with circulating various solid particles. The present work showed that the drag force coefficients of particles in the internal flow were higher than in the external flow, in addition, they were lower with the shapes of particles being closer to the spherical geometries.
