研究领域

微尺度流体传递过程实验室致力于探索微细通道内流体动量、能量及化学成分的传递规律,并根据其规律设计微型分析检测设备、微型蒸发冷凝设备;借鉴微尺度传递机理,设计微纳结构表面,实现大尺度气固、液固两相分离过程强化。 液相色谱的分离性能与孔隙结构密切相关,微加工技术为控制微观孔隙结构提供了可能。因此采用微加工技术制备的微型液相色谱柱相比于传统的颗粒填充色谱柱具有更大的优势。本实验室在液相色谱动力学理论,高效色谱柱结构设计方面开展研究,取得了一些成果。 新型色谱柱结构 胶体晶体内传质动力学理论 颗粒填充色谱柱内传质动力学 微型气相色谱采用微通道代替经典的毛细管,具有结构设计灵活、便于集成、分离性能高等优点,有望满足野外在线检测的需求。为提高微型气相色谱性能,本实验室在动力学模型、微通道结构优化方面开展了一系列工作,开发成功微通道截面优化工具,提出优化微通道色谱柱截面形貌。 微通道色谱柱截面形貌优化 微通道在电子器件散热中应用广泛,理解气体在通道内的压降及传热性能对优化微通道散热器至关重要。本实验室开展了气体在微通道内的流动传热特性数值模拟,取得了一些成果。 计算流体动力学(CFD)可辅助设计大量能源化工设备与系统。已完成及正在进行的内容包括旋风分离器设计,微通道换热器模拟,厂房供排风系统设计,低温流体空温汽化器设计软件开发。 厂房污染物排放系统设计 微通道冷凝器冷凝过程预测与优化
