级联系统平衡时间探究

在级联系统工况转换时,流体状态很容易达到新定常态,而丰度分布却需要更长的时间才可达到新定常态。通过理论推导,给出了特定情况下估算小分离系数和大分离系数级联系统平衡时间的表达式,并简要分析了可行的工况转换方法。研究表明:在相同工况下,大分离系数的级联平衡时间远远小于小分离系数的级联平衡时间,即分离系数越大,其级联平衡时间越短。

Exploration of Equilibrium Time of the Cascade System

During the transformation of cascade system conditions the fluid state easily reach new norm,and the abundance distribution is need more time to achieve.Through theoretical derivation method,the equilibrium time expression of the big and small separation factor of cascade system in the specific case are given,and the feasible condition transformation method is briefly analyzed.Under the same conditions,the qualitative comparison,obviously,big separation factor of the cascade,the equilibrium time is far less than the equilibrium time of small separation factor of the cascade.The separation factor is the greater,the cascade equilibrium time become the shorter.
