was modeled with RNG k-ε model. The simulations were conducted to study the variations of liquid film hydrodynamics with countercurrent gas load (F factor) over Mellapak 250Y corrugated packing sheet... packing; countercurrent gas flow; F factor 精馏和吸收过程中气液两相流场分布和界面传质是目前业内研究的焦点[1].基础实验测试和分析研究的不足,"效率驼峰",液泛等机理尚不能完全掌握,这阻碍了分离效率的进一步提高.因此有必要对精馏过程中气液两相流体力学特性进行进一步地研究和探索[2].就目前而言,对于规整填料塔内大规模流动和传质过程的模拟还是无法采用直接数值模拟的方法......
:由于钙钛矿型材料具有广泛的应用前景,因此对其结构及物理,化学性质的研究一直是材料研究领域的热点之一.其中,利用容许因子(Tolerance factor)来预测钙钛矿型材料的结构稳定性可以帮助研究者发现更多的新型功能材料,而传统的基于离子半径定义的容许因子tIR存在一定的局限性.本文基于SISSO(Sure independence screening and sparsifying...

strain to neighboring grains (termed as twin-twin transfer behavior). A geometric compatibility factor was discussed to assess the possibility. It indicates that the more similar of grain orientation and the larger of value are, the more likely twin-twin transfer tends to happen.
