非均质移动颗粒床的渗流换热模型与数值模拟
Seepage heat transfer model and numerical simulation for heterogeneous moving particulate bed
摘要
Abstract
For heat transfer process in a heterogeneous moving particulate bed, a mathematical model for the seepage heat transfer process was established. The COADI-GS algorithm was proposed to solve thermally coupled flow of gas-solid heat transfer process numerically. The comparison for the simulation results on the heat transfer models for homogeneous and heterogeneous moving beds demonstrates that the temperature distributions in the two beds are quite different and the model for the heterogeneous moving particulate bed is more accurate for the seepage and heat transfer process in the bed. The results show that the increase of wind pressure is conducive to the cooling of clinker particles, but it may reduce the temperature of recovered wind. The particle temperature increases with the moving speed almost linearly.关键词
