逆流色谱仪是一种新颖的无载体液液分配色谱仪器。近年来,由于旋转螺旋管内溶剂系统的单向性分布现象的发现,使这种仪器的分离时间大大的缩短,分离效率进一步提高。但是,已见报导的仪器都只应用了两维离心力场的作用来支撑液态的固定相,而本文介绍的正交轴逆流色谱仪则应用了三维场的作用。使固定相在大内径的管柱里的保留值提高,一次分离样品的量可高达克量级,而且仪器能在较低的转速下运行,平衡稳定性明显改善。本文简要说明了这种仪器的原理、结构和特征,并给出了制备分离甾族反应混合物、吲哚类植物激素、二硝基苯氨基酸的应用结果。

By using the so-called "quasi-3-D" boundary layer equations, the Thwaites's method for 2-D laminar boundary layer and the Truckenbrodt's method for 2-D turbulent boundary layer are extended to incorporate the 3-D effects so that an iterative solution for the boundary layer development on a rotating helical blade is found.

The boundary layer on a rotating helical blade is a typical three-dimensional one. By using the so-called "quasi-3-D" boundary layer equations, the Thwaites's method for 2-D laminar boundary layer and the Truckenbrodt's method for 2-D turbulent boundary layer are extended to incorporate the 3-D effects so that an iterative solution for the boundary layer development on a rotating helical blade is found. This method has been applied in rotating disk and a helical blade of large chord length. Comparison with the exact analytical solution and the measurements made by Lakshminarayana and others respectively shows that it can be used in the calculation of the boundary layer on blades of a ship propeller.
