摘要
流场速度分布均匀性在众多领域中都有所应用,但目前对其尚无统一的评价指标。通过比较不同领域的速度场均匀性评价指标,分析各种评价指标的作用,并通过一种理论模型,寻找各种指标之间的关系,为今后研究流场速度分布均匀性评价指标选择提供参考。
Flow velocity distribution uniformity is widely applied in many fields,but it has no unified evaluation index till now.A variety of indices play a unique role in their respective field.A comparison between the evaluation indices in different fields was carried out to analyze their respective functions.A theoretical model was applied to figure out relationship between each evaluation indices,which can provide references for selecting evaluation index in future research.Meanwhile,these indices were used in experimental results of velocity distribution in hot blast stove model,to analyze the characteristics that each index reflected in common flow field.
