基于Fluent的固定床生物质气化炉冷态压力场研究（Analysis of Fixed-bed Biomass Gasifier Cold Internal Pressure Field Based on Fluent）
生物质气化 下吸式气化炉 数值模拟
2010/12/29
以下吸式固定床生物质气化炉物理模型为研究对象，应用流体仿真软件Fluent，对冷态气化炉在单、双层气化剂配风工况下的床层压力场进行仿真研究。通过气化炉多点测压实验，对仿真结果进行验证。利用欧拉-拉格朗日方法分析气化炉冷态流场分布特性，根据伯努利方程说明气化炉床层压力场的变化原因。结果表明，仿真与实验结果的误差值在2.5%以内，气化剂配风工况的变化改变了炉内流场，双层气化剂配风使氧化层压力场平均值...
