AbstractCTS-0109079D. D. Joseph, University of MinnesotaThe proposed effort is a GOALI association between the University of MinnesotaFluid Dynamics Lab and the oil-industry supported laboratory STIMLAB from Duncan, Oklahoma. It is an attempt to explore the application of the direct numerical simulation technique to slurry transport and also to proppant transport in reservoir fractures. In both cases, the emphasis will be to identify the force interaction between the particles and the ambient liquid. Also, numerical flow field calculations will be fitted to experimental results with the help of relevant non-dimensional power law parameters. This "method of correlations" should reveal self-similar properties not immediately apparent from the traditional conservation equations of fluid dynamics.The PI presents an extensive evaluation of the progress he has already accomplished in that direction, in part with NSF support. Many results have been obtained for a variety of applications, from the simple (Poiseuille flow) to the very applied (foaming bubble columns, bitumen froth transport...). Several finite element codes have been evolved (ALE, DLM), and successful correlations (some of them by other groups) are presented. Out of this abundance of results, the PI has produced a number of proposed research extensions into interdependent properties: particle life off, circulation, bifurcation, and levitation to equilibrium. A partial outline of the correlations which the PI intends to investigate is given, as well as a short statement of the more applied kind of problems where STIMLAB could use its abundant data bank: proppant transport, collision models.

abstractcts - 0109079 d。明尼苏达大学流体动力学实验室和石油工业支持的来自俄克拉何马州邓肯市的STIMLAB实验室是一个合作项目。探讨了直接数值模拟技术在储层裂缝中浆体运移和支撑剂运移中的应用。在这两种情况下，重点将是确定粒子和周围液体之间的力相互作用。同时，利用相关的无因次幂律参数，将数值流场计算与实验结果拟合。这种“相关性方法”应该揭示出在传统流体动力学守恒方程中无法立即显现的自相似特性。在国家科学基金会的部分支持下，PI对他在这个方向上已经取得的进展进行了广泛的评估。许多结果已经获得了各种应用，从简单的（泊泽维尔流）到非常应用的（起泡柱，沥青泡沫输送…）。几个有限元代码已经发展（ALE， DLM），并提出了成功的关联（其中一些是由其他小组）。在这些丰富的结果中，PI提出了许多关于相互依赖性质的研究扩展：粒子生命、循环、分岔和平衡悬浮。给出了PI打算研究的相关性的部分大纲，以及对STIMLAB可以使用其丰富数据库的更适用类型问题的简短说明：支撑剂运输，碰撞模型。
