为了预测复杂孔隙结构中毛管压力主导下两相流排驱过程中的流体分布,从仿真多孔介质和岩石CT图像中抽取子样本,并采用孔隙形态模拟器(PMS)生成流体分布,以创建多样化的数据集,将距离图及像素大小、界面张力、接触角、压力作为输入参数,通过改造、训练、评估卷积神经网络(CNN)、递归神经网络(RNN)和视觉转换器(ViT),优选用于预测流体分布的模型。模拟分析表明,常用的卷积和递归神经网络在捕捉流体连通性方面存在不足。基于ViT构建了一个高维视觉转换器(HD-ViT),该转换器先忽略孔隙的空间位置仅根据其大小进行排驱,再在后处理步骤中追加流体连通要求,这种方法允许在任何坐标方向预设出入口,并使用不同尺寸和不同分辨率的图像进行渗流状态推断。通过在砂岩和碳酸盐岩大图像上验证,并与微流控驱替测试的实验结果比较,证实了HD-ViT模型的有效性、精确性和速度优势,且在捕捉孔隙尺度三维流动方面存在较大的潜力。

Feynman-Path Integral in Banach Space: In 1940, R.P. Feynman attempted to find a mathematical representation to express quantum dynamics of the general form for a double-slit experiment. His intuition on several slits with several walls in terms of Lagrangian instead of Hamiltonian resulted in a magnificent work. It was known as Feynman Path Integrals in quantum physics, and a large part of the scientific community still considers them a heuristic tool that lacks a sound mathematical definition. This paper aims to refute this prejudice, by providing an extensive and self-contained description of the mathematical theory of Feynman Path Integration, from the earlier attempts to the latest developments, as well as its applications to quantum mechanics. About a hundred years after the beginning of modern physics, it was realized that light could in fact show behavioral characteristics of both waves and particles. In 1927, Davisson and Germer demonstrated that electrons show the same dual behavior, which was later extended to atoms and molecules. We shall follow the method of integration with some modifications to construct a generalized Lebesgue-Bochner-Stieltjes (LBS) integral of the form , where u is a bilinear operator acting in the product of Banach spaces, f is a Bochner summable function, and μ is a vector-valued measure. We will demonstrate that the Feynman Path Integral is consistent and can be justified mathematically with LBS integration approach.
