摘要
综述了牛顿流体在放置了各向同性和各向异性预制件的RTM平板模具中二维径向恒流和恒压渗流的流动模型。对各个模型的可测量物理量之间的关系通过求解其解析解进行了必要的拓展补充推导和研究分析 ,对传统的二维解析方程进行了拓展和改进 ,提供了在不透明模具中测定渗透率的方法。即在恒流条件下利用压力传感器和恒流泵测定预制件的二维渗透率 ;或者在恒压条件下利用数字流量计和压力表测得二维渗透率。
In this article 2 D radial flow in planar isotropic and anisotropic preforms has been reviewed. A theoretical model has been developed for obtaining preform permeability in RTM mould without transparent mould. With equations described, data on inlet pressure vs. time for constant flow rate of mold filling, or data on flow rate vs. time for constant pressure of mold filling can be used for calculatng preform permeability.
