焦炭下降运动的势流模型及实验验证

Potential Flow Model of Coke Descending Movement and Experimental Verification

利用势流模型对干熄炉内焦炭下降运动进行了数值模拟,并针对干熄炉模型实验结果进行了对比验证。结果表明,势流模型基本上能够准确地反映炉型变化和风帽对焦炭下降运动的影响,但无法描述壁面摩擦阻力的影响。

By means of potential flow model, the numerical analogue was made for coke descending movement in CDQ cooling chamber, against the experimental resul ts on CDQ cooling chamber model the comparison verification was made. The result s show that the potential flow model can basically and correctly reflect the var iation of chamber type and influence of vent cowl on coke descending movement, h owever there is no way to describe the influence of wall friction resistance.
