简介:为研究冰片与β-环糊精(β-cD)或羟丙基-β-环糊精(HP-β-CD)包结机理,并解释冰片与两者的相溶解度关系,利用Accelrys公司开发的MaterialsStudio4.0进行分子动力学模拟实验。在Compass力场下建立晶胞模型并进行恒温恒容(NVT)和恒温恒压(NPT)模拟得出能量图。两个能量图均显示发生包结作用的范德华力远大于氢键与疏水作用力之和,这证明冰片与环糊精发生包结作用的主要驱动力是范德华力。能量图显示:冰片与β-环糊精包结物的结合能低,而冰片与羟丙基-β-环糊精包结物的结合能高;故冰片与β-环糊精形成不溶性包结物,冰片与羟丙基-β-环糊精形成可溶性包结物。
简介:摘要:本文基于数值模拟方法,对气烧套筒窑燃烧过程中的温度场进行了模拟与分析。通过建立数学模型和计算流体力学模拟,研究了不同工况下的温度场分布规律和变化趋势。结果表明,在不同燃烧条件下,温度场分布存在差异,且燃烧室内部温度分布不均匀。本文的研究结果为优化窑炉燃烧工艺提供了理论依据。
