Examples
- First , according to the demand of vimp for resin system , the reaction kinetics and rheological of up resin are investigated and the optimal content of low additive profile ( lpa ) is determined . then vimp based on a high - permeable medium and grooves are studied by visual experiments , through which the appropriate high - permeable mediums are selected and the parameters of width , depth and spacing for flow grooves and spacing for supply grooves are optimized . furthermore , various factors affecting the mold filling process are discussed and the whole vacuum infusion procedures are described taking examples of the manufacture of a model boat and a sandwich panel in one infusion
文中首先根据vimp对树脂体系的要求，对vimp用不饱和聚酯树脂体系的动力学和流变学性能进行了研究，确定了最佳低收缩添加剂的含量；对高渗透介质型和沟槽型vimp开展了实验研究，通过可视化实验优选出较好的高渗透介质，确定了引流槽的宽度、深度和槽间距及主槽的槽间距等工艺参数并进行了优化；对影响充模过程的各种因素进行了详细的讨论，并以模型船和夹芯面板的制作为实例描述了两种vimp的成型过程；在实验的基础上，建立了二维渗漏模型，采用控制体有限元法对高渗透介质型vimp进行了成型过程的计算机模拟计算，通过充模时间和流动前峰的计算值与实验结果的比较，验证本文所采用的数学模型和数值方法的正确性，其结果对实际生产具有一定的理论指导意义。 - The influence of the boundary on the seepage flooding in low permeability porous media ca n ' t be ignored when the thickness of boundary layer reaches a critical value . the larger the thickness of boundary layer is , the more obvious the nonlinear flow is . 4 . factors affecting boundary layer are studied systemically , the mathematical expression of porous flow based on the experiment is derived
吸附边界层的厚度大到一定程度将对低渗透介质中渗流规律产生影响，边界层厚度越大，非达西现象越明显； 4 、系统研究了影响边界层的因素，并在实验的基础上，推导了考虑边界层影响下的渗流力学表达式。
