传统化工反应器是刚性的,反应器壁不可伸缩或运动,因此反应器内物料的输送、混合等过程需借助于诸如泵、搅拌器等其他辅助设备。然而,传统机械搅拌的方法在处理高粘性物料时有很大的局限性,尤其在低雷诺数的情况下,反应器内物料往往存在严重的浓度分布不均的现象。此外,由于传统硬式反应器的器壁是固定不动的,因而物料很容易粘附或沉积于反应器壁上产生结垢问题。从某种意义上来说,人体小肠可以看作是一种功能复杂的管式反应器。该“反应器”利用其独特的蠕动功能实现了高粘性物料的混合、运输和反应,且有效避免了物料在“反应器壁”上的结垢。 基于以上提到的诸多原因,本研究便利用仿生方法学的原理,模仿人体小肠生理结构及功能,设...The traditional chemical reactors are rigid, and the reactor walls are not able to contract or squirm, as a result, the transport and mixing of material in the reactors have to rely on other auxiliary equipments, such as pumps, agitators etc. However, there are great limitations for the conventional mixing methods, especially for mixing high viscosity fluids at low Reynolds numbers. The phenomenon...学位:工学博士院系专业:化学化工学院_化学工程学号:2062011015365
