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.

流化实验数据集

本数据集采用粒径分别为250 μm、125 μm、90 μm及63 μm的巴洛蒂尼玻璃微珠（Ballotini glass beads）构成颗粒柱，在一系列剪切速率（γ̇ = 0、16、49、115、213 s⁻¹）下开展剪切实验，同时以递增的空气通量速率对颗粒柱进行流化处理。数据集包含各粒径级分与各剪切速率对应的颗粒柱压力梯度Δp（单位：Pa）及相应空气通量速率Q（单位：L·min⁻¹）。
