关联数据是一项微妙的任务，其中最好的也是最差的。本文对文、余简化法求最小流化速度的方法进行了改进，指出了文、余简化法与Ergun方程同时使用的科学上的不便。本研究已经证明了矛盾推导出同时使用这些文和俞关系，因为它是最小流化速度的情况下。文和于的方法，其中包括同时消除床层空隙率在最小流化和颗粒球形度从最小流化速度计算仍然是明确的科学错误，应该避免。文和余的关联式的使用，然后建议的变化，以提高，一方面，预测精度的最小流化速度计算，另一方面，科学的准确性，这一普遍接受的工程方法。新方法的性能显着提高了最小流化速度的预测。
Correlating data is a delicate task where the best is among the worse. The present study aims at presenting an improvement of the use of Wen and Yu simplifications for minimum fluidization velocity having presented the scientific awkwardness contained in the usual method of using their or similar relations simultaneously in combination with Ergun's equation. The present study has demonstrated the contradiction deduced from the simultaneous use of these Wen and Yu relations as it is the case for the minimum fluidization velocity. The method of Wen and Yu which consists of simultaneously eliminating the bed voidage at minimum fluidization and particle sphericity from the minimum fluidization velocity calculation remains definitively scientifically wrong and should be avoided. A change in the Wen and Yu's correlations use is then suggested to increase, on the one hand, the prediction accuracy for the minimum fluidization velocity calculation, and on the other hand, the scientific exactness of this generally received engineering method. Performances of the new method significantly improves the prediction of minimum fluidization velocity.
