EXPERIMENTAL STUDY OF THE POWER NUMBERS FOR AGITATING BEDS OF SOLID PARTICLES WITH MULTIPLE BLADES AND UPWARD STREAMS OF GAS LESS THAN Umf

[摘要] References(2)Cited-By(5)The relation between Np and NM in the previous paper has been extended further to the power characteristics for agitating solid beds with multiple blades of various pitches and when accompanied with upward streams of gas through the beds. By using the correction factor, k, the modified nondimensional numbers in the following terms; ???? can also be correlated by the same equation in the previous paper as follows,NP = 20NM-1 + 50 The gas flow rate, ump, which gives the minimum total power requirement for the upward gas flow and the mechanical agitation has been calculated mathematically and ensured experimentally.
