the expansion ratio is related to the liquid flow rate, fluidization velocity and free descending velocity of the packing material.
填料膨胀率的大小与液体流量、填料的流化速度及自由沉降速度有关。
in this paper, the influence of temperatures on the critical fluidization velocity was analyzed theoretically at first.
本文首先从理论上分析了温度对气固流化床的临界流化速度的影响。
the minimum fluidization velocity has a minimum value when the frequency of sound waves approached 150 hz, whereas it decreased as the sound pressure level was increased at the same sound frequency.
