项目摘要
Novel morphological instabilities and phase changes generated by localized reactions in interfacial regions between reacting fluids can be found in physical, biological and engineering systems such as smoldering flame fronts, biomembrane formation, and oil recovery systems. For instance, the formation of solid-like gels at water-oil interfaces during oil recovery processes can be unfavorable because gel build-up can clog wells and pipelines. On the other hand, gel formation can actually be beneficial in flow diversion processes by diverting the flow away from porous rocks and enhancing oil recovery. The interface dynamics and morphologies of this open system cannot be predicted solely by an equilibrium phase diagram, and mathematical models and numerical simulations are needed to fully characterize the nonlinear, out-of-equilibrium dynamics. This project aims to establish a computational framework for models of non-equilibrium phenomena, and design algorithms and experiments to investigate the interface dynamics of complex, reactive fluids. This project will also provide interdisciplinary training for students, and research activities will help develop the next generation of mathematicians, scientists and engineers. The team of PIs consists of the three researchers from three different institutions, where training of graduate students on the topics of the project is expected. Studies of two or more fluids that are reactive, and flow through a porous medium, are fundamental to many fields. At equilibrium, the mixture may behave like a liquid or a gel (viscoelastic solid) depending on the concentrations of the components according to an equilibrium phase diagram. When driven out of equilibrium by, for instance, injection of one fluid into another, the morphology of the expanding interface between them can be very complex and strongly depends on an interplay between thermodynamic phase behavior and hydrodynamic forces. This project builds upon breakthroughs in modeling, computation, and experimental techniques to develop a unified mathematical framework that resolves the interface dynamics of reactive fluids driven out of equilibrium. Thermodynamically consistent equations governing the non-equilibrium dynamics of ternary reacting systems of immiscible fluids will be derived, focusing on the radial Hele-Shaw geometry as a prototype. Both sharp interface and diffuse interface numerical schemes (energy-stable, adaptive finite-difference methods using scalar auxiliary variables) will be developed and validated against asymptotic reductions to sharp interface models and new experimental data generated from this project. The integrated mathematical, computational and experimental approach will provide a framework for understanding the nonequilibrium dynamics, predicting the emergence of complex patterns and developing strategies for controlling the pattern formation process in fundamental multiphysics interface problems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
在物理、生物和工程系统中,如阴燃火焰前缘、生物膜形成和采油系统中,可以发现由反应流体之间的界面区域中的局部反应产生的新型形态不稳定性和相变。例如,在采油过程中在水-油界面处形成固体状凝胶可能是不利的,因为凝胶积聚可能堵塞威尔斯和管道。另一方面,凝胶形成实际上可以通过使流动远离多孔岩石而在流动转向过程中是有益的,并提高石油采收率。这个开放系统的界面动力学和形态不能仅仅通过平衡相图来预测,需要数学模型和数值模拟来充分表征非线性、非平衡动力学。 本计画旨在建立一个非平衡现象模型的计算架构,并设计演算法与实验来研究复杂反应流体的界面动力学。该项目还将为学生提供跨学科培训,研究活动将有助于培养下一代数学家,科学家和工程师。PI团队由来自三个不同机构的三名研究人员组成,预计将对研究生进行项目主题的培训。研究两种或两种以上的反应性流体,并通过多孔介质流动,是许多领域的基础。在平衡时,根据平衡相图,取决于组分的浓度,混合物可以表现得像液体或凝胶(粘弹性固体)。当例如通过将一种流体注入另一种流体而被驱动出平衡时,它们之间的膨胀界面的形态可能非常复杂,并且强烈依赖于热力学相行为和流体动力学之间的相互作用。该项目建立在建模,计算和实验技术的突破基础上,开发了一个统一的数学框架,解决了反应性流体脱离平衡的界面动力学问题。热力学一致性方程的不混溶流体的三元反应系统的非平衡动力学将推导出,侧重于径向Hele-Shaw几何作为原型。将开发锐界面和扩散界面数值方案(使用标量辅助变量的能量稳定自适应有限差分法),并根据锐界面模型的渐近简化和本项目产生的新实验数据进行验证。综合数学,计算和实验的方法将提供一个框架,了解非平衡动力学,预测复杂模式的出现,并制定战略,控制模式的形成过程中的基本multiphysics接口problems.This奖项反映了NSF的法定使命,并已被认为是值得通过评估使用基金会的智力价值和更广泛的影响审查标准的支持。
