摘要
在 0.5, 1.0, 1.5 和 2.0 MPa 的不同压力下面的石英沙和玻璃祷告的最小的使液化速度被调查。最小的使液化速度与增加压力减少。到最小的使液化速度的压力的影响比为更小的为更大的粒子是更强烈的。基于测试结果和 Ergun 方程,最小的使液化速度的一个经验方程被建议,计算结果比得上另外的研究人员鈥 ? 结果。
Minimum fluidization velocity of quartz sand and glass bead under different pressures of 0.5, 1.0, 1.5 and 2.0 MPa were investigated. The minimum fluidization velocity decreases with the increasing of pressure. The influence of pressure to the minimum fluidization velocities is stronger for larger particles than for smaller ones. Based on the test results and Ergun equation, an experience equation of minimum fluidization velocity is proposed and the calculation results are comparable to other researchers' results.
