    • A fuel system for an energy conversion device includes a deoxygenator system with a multitude of flow impingement elements which are interleaved to provide a fuel channel with intricate two-dimensional flow characteristics. The flow impingement elements break up the boundary layers and enhance the transport of oxygen from the core of the of the fuel flow within the fuel channel to the oxygen permeable membrane surfaces by directing the fuel flow in a direction normal to the oxygen permeable membrane. The rapid mixing of the relatively rich oxygen core of the fuel with the relatively oxygen-poor flow near the oxygen permeable membrane enhances the overall removal rate of oxygen from the fuel. Because this process can be accomplished in fuel channels of relatively larger flow areas while maintaining laminar flow, the pressure drop sustained is relatively low.
    • 用于能量转换装置的燃料系统包括具有多个流动冲击元件的脱氧器系统,其被交错以提供具有复杂二维流动特性的燃料通道。 流动冲击元件通过沿着与透氧膜垂直的方向引导燃料流而分解边界层并增强氧从燃料通道内的燃料流的核心输送到氧气渗透膜表面。 燃料的相对富氧核心与氧气渗透膜附近的相对贫氧流的快速混合提高了氧气从燃料中的总体去除速率。 因为该过程可以在维持层流的同时在相对较大的流动区域的燃料通道中实现,所以压力下降相对较低。
