摘要： A system and method for enhancing the selective transport of fluid particles through a semipermeable membrane. The system consists of a conduit, comprising a semipermeable membrane, containing within it a plurality of sheet-like elements extending longitudinally within said conduit. Means are provided for flowing a first fluid through said conduit. Means are also provided, either for receiving the permeate passing through said semipermeable membrane or for submerging said semipermeable membrane in a second fluid. Each sheet-like element in the conduit is curved to turn the direction of fluid flow by being arranged in alternating right- and left-handed curvature groups (a group consisting of one or more elements). As a result, each particle of the fluid flowing through said conduit is moved in a programmed manner toward and away from the wall of the conduit. The semipermeable membrane selectively passes certain particles of at least one of the fluids. In one type of application, such passage tends to create a condition, commonly called ''''polarization,'''' in the fluid layer adjacent the inner wall of the conduit which decreases the rate at which the selected fluid particles pass through the semipermeable membrane. The action of the curved elements removes such layer from the inner wall, thus overcoming the inhibiting effect of such layer on the transport of the selected fluid particles through the membrane. In another type of application, in which a polarization layer is not formed, but in which it is desirable to distribute the fluid material adjacent such inner wall under non-turbulent conditions, the curved elements effectively produce the desired results without resorting to turbulent flow.
摘要翻译：一种用于增强流体颗粒通过半透膜的选择性输送的系统和方法。该系统由包括半透膜的导管组成，其中包含多个在所述管道内纵向延伸的片状元件。提供了用于使第一流体流过所述导管的装置。还提供了用于接收通过所述半透膜的渗透物或将所述半透膜浸没在第二流体中的装置。导管中的每个片状元件被弯曲以通过布置在交替的左右曲率组（由一个或多个元件组成的组）中来转动流体流动的方向。结果，流过所述导管的流体的每个颗粒以编程的方式移动并且远离导管的壁。半透膜选择性地通过至少一种流体的某些颗粒。在一种类型的应用中，这种通道倾向于在邻近管道内壁的流体层中产生通常称为“极化”的状态，这降低了所选择的流体颗粒通过半透膜的速率。弯曲元件的作用从内壁去除这样的层，从而克服了这种层对所选择的流体颗粒通过膜的输送的抑制作用。在另一种类型的应用中，其中没有形成偏振层，但是在非湍流条件下希望将流体材料分布在这种内壁附近，所以弯曲元件有效地产生期望的结果而不求助于湍流。
