Permeability of granular mixtures under shear

Data set for fluidisation experiments A granular column cmprising Ballotini glass beads of diameters 250 μm, 125 μm, 90 μm and 63 μm is sheared at a range of shear rates, γ˙ = 0, 16, 49, 115, 213 s−1, whilst simultaneously being fluidised with an increasing air flux rate. The data set includes the values of the pressure gradient across the granular column, Δp (Pa) and the corresponding air flux rate, Q (L min-1), for each size fraction and each shear rate.流态化实验数据集 本数据集针对由粒径分别为250 μm、125 μm、90 μm及63 μm的巴洛蒂尼玻璃微珠（Ballotini glass beads）构成的颗粒柱，在一系列剪切速率γ̇=0、16、49、115、213 s⁻¹的条件下施加剪切作用，同时以递增的空气通量速率对其进行流态化处理。 本数据集包含各粒径分级与各剪切速率下，跨颗粒柱的压力梯度Δp（Pa）以及对应的空气通量速率Q（L·min⁻¹）的实测数值。
