【正文】 雜在廣泛分布式進(jìn)料是因?yàn)榇嬖谝徊糠至魇\(yùn)走了不屬于懸浮床的部分。由于缺乏密度效應(yīng)和規(guī)模效應(yīng)的優(yōu)勢在分選性能同時低床層壓力下在其他地方討論（薩卡等人， 20xx 年）。從圖中可以看出，當(dāng)該懸浮液密度被修改時，匹配實(shí)驗(yàn)數(shù)據(jù)和計算的數(shù)據(jù)是顯著改善的。該模型預(yù)測較高的懸浮密度該計算和實(shí)驗(yàn)結(jié)果之間存在不匹配。該模型有用合理的精度預(yù)測 FDS 的性能的作用。 我們對 進(jìn)料粒度分布的影響也進(jìn)行了研究。 模擬研究證明任何條件下是對于一定的尺寸 范圍內(nèi)的顆粒的密度分離合適的，而 其他 尺寸大小的阻礙分離性能。 針對實(shí)驗(yàn)數(shù)據(jù)預(yù)測的結(jié)果進(jìn)行驗(yàn)證。 參考文獻(xiàn)： Asif, M., 1998.
