uniform velocity distribution

The radial distribution of particle velocity is more uniform and the difference between the maximum velocity and the minimum velocity decreases in comparison with the conventional riser.

与传统提升管相比，环形截面提升管中颗粒速度分布的均匀性有所改善，其最高速度与最低速度之差变小。

The improvement indicates that the distribution of outlet velocity is more uniform and exhaust resistance decrease obviously. It can raise the total capability of equipment effectively.

计算结果表明改进后的排汽缸出口速度分布更加均匀，排汽损失明显降低，可有效提高机组整体性能。

Complex patterns of flue gas and non-uniform temperature distribution along furnace height were taken place due to high jet velocity of bottom burners in the ethylene cracking furnace.

乙烯裂解炉底部燃烧器的燃气射流，使炉内烟气流动复杂，烟气温度分布的均匀性较差。
