GOALI: Direct Numerical Simulation of Slurry Transport Focusing on Engineering Correlations

摘要CTS-0109079 D。D.约瑟夫，明尼苏达大学拟议的努力是明尼苏达大学流体动力学实验室和石油工业支持的实验室STIMLAB从邓肯，俄克拉荷马州之间的GOALI协会。 这是对直接数值模拟技术在储层裂缝中泥浆运移和支撑剂运移中应用的一次尝试。 在这两种情况下，重点将是确定粒子和周围液体之间的力的相互作用。 此外，数值流场计算将拟合实验结果的帮助下，相关的无量纲幂律参数。 这种“相关性方法”应该揭示自相似特性，而不是从传统的流体动力学守恒方程中立即显现出来。PI对他在这个方向上已经取得的进展进行了广泛的评估，部分是在NSF的支持下。 从简单的（Poiffille流动）到非常实用的（发泡泡罩塔、沥青泡沫输送.），已经针对各种应用获得了许多结果。 几个有限元代码已经发展（ALE，DLM），并成功的相关性（其中一些由其他团体）。 在这些丰富的结果中，PI已经提出了一些相互依赖的性质的研究扩展：粒子寿命，循环，分叉和悬浮到平衡。 给出了PI打算调查的相关性的部分概要，以及STIMLAB可以使用其丰富数据库的更实用的问题的简短陈述：支撑剂运输，碰撞模型。

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.
