Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：斜坡上浅水波的研究进展
斜坡 上浅水波 泄洪渠
2023/5/6
在倾斜的泄洪渠上，水流往往不是等高的层流，会形成周期滚动激波，简称滚波。由于滚波的水深不是常值，其激波处的水深必定比相同泄洪量层流大。为了避免洪水外溢导致的非必要经济损失，滚波强度与泄洪渠坡度、截面形状、渠宽等变量之间的关系是水利工程学研究的主要问题之一。数学上，假设流体垂直尺度远小于水平尺度，对三维自由表面无旋不可压Navier-Stokes 方程做垂直方向的积分，我们得到Saint-Venan...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：页岩/致密非常规油气藏多尺度多场耦合数值模拟及应用
页岩/致密 非常规油气藏 多尺度多场耦合 数值模拟
2023/5/5
我国页岩/致密非常规油气资源丰富，是增储上产的现实领域。我国页岩/致密非常规油气藏储渗空间的孔隙类型多样，包括基质孔隙系统和复杂裂缝系统，非均质性极强，且跨越多个尺度。与此同时，随着开发的不断深入，目前已进入埋藏大于3000米的深层非常规油气资源勘探开发阶段，裂缝和孔隙在开发过程中易发生变形，具有强应力敏感性。本报告将主要介绍页岩/致密非常规油气藏开发中的多尺度以及热流固耦合问题的数值模拟方法、模...
