Multiphase flow through permeable media is sophisticated in nature because phases interact at pore scale and compete for permeability. This complexity and non-linearity make predictive mathematical descriptions a challenging task. Remediation of aquifer NAPL (non-aqueous-phase liquid) contamination is an example of an application where predictive models are highly desirable. This dissertation presents an experimental program that uses a microfluidic experiment at form, a high-resolution camera, and a microscope-mountable high-speed camera to examine i) the flow behavior of remediation of aquifer contamination using CO2 foams that are stabilized with nanoparticles, ii) transient flow states in single-phase flow, and iii) occurrence of Haines Jump in two-phase flow using an evolution graph produced through interface tracking. Contamination caused by NAPL in aquifers and soil presents a big challenge and affective remediation techniques are desired. This work considers CO2 foams for remediation of NAPL contaminated porous media. However, CO2-surfactant foam is not stable enough for efficient removal of NAPL contamination. This shortcoming may be alleviated via the NP-surfactant mixture as a stabilizing agent. The first part of work focuses on the use of fly ash NPs and a mixture of AOS and LAPB surfactants to generate stable foams. This work presents results from an experimental program that was designed to establish optimum concentration of the foam’s constituents. Results indicate that fly ash, which is a by-product of coal-burning power plants, is a suitable material to generate robust CO2 foams. Moreover, the results suggest for 1000 ppm AOS-LAPB surfactant solution, 1000 ppm fly ash NPs is the best choice. What’s more, foam generated in channels is discontinuous and the solid sediment in NAPL can weaken the mobility and performance of foam. The flow system is too complex to study the mechanics behind the multi-phase flow. Hence, simplified microfluidic devices and advanced techniques are applied in the second and third part of the dissertation. The classic multiphase extension for Darcy's law models this complexity through two practices: per-phase application of Darcy's law with relative permeability and instantaneous resolution of fluid dynamics at pore scale. Experimental evidence against the latter practice is provided in the second part in the dissertation for single-phase experiments. The third part of the dissertation targets the former assumption by examining Haines Jump, a type of rapid pore-filling event in multiphase flow through permeable media better known as Haines Jump. Segmentation and tracking techniques are applied to extract and track displacement fronts as they evolve through high-speed video recording. The resulting evolution graph facilitate topology-cognitive computation on the transport network. These experiments conclusively identify Haines Jump in microfluidic devices and qualitatively analyze their significance to Darcy's law in the macroscopic scheme of bulk flow rates.

A microfluidic biochip is an engineered fluidic device that controls the flow of analytes, thereby enabling a variety of useful applications. According to recent studies, the fields that are best set to benefit from the microfluidics technology, also known as lab-on-chip technology, include forensic identification, clinical chemistry, point-of-care (PoC) diagnostics, and drug discovery. The growth in such fields has significantly amplified the impact of microfluidics technology, whose market value is forecast to grow from $4 billion in 2017 to $13.2 billion by 2023. The rapid evolution of lab-on-chip technologies opens up opportunities for new biological or chemical science areas that can be directly facilitated by sensor-based microfluidics control. For example, the digital microfluidics-based ePlex system from GenMarkDx enables automated disease diagnosis and can bring syndromic testing near patients everywhere. However, as the applications of molecular biology grow, the adoption of microfluidics in many applications has not grown at the same pace, despite the concerted effort of microfluidic systems engineers. Recent studies suggest that state-of-the-art design techniques for microfluidics have two major drawbacks that need to be addressed appropriately: (1) current lab-on-chip systems were only optimized as auxiliary components and are only suitable for sample-limited analyses; therefore, their capabilities may not cope with the requirements of contemporary molecular biology applications; (2) the integrity of these automated lab-on-chip systems and their biochemical operations are still an open question since no protection schemes were developed against adversarial contamination or result-manipulation attacks. Optimization of Trustworthy Biomolecular Quantitative Analysis Using Cyber-Physical Microfluidic Platforms provides solutions to these challenges by introducing a new design flow based on the realistic modeling of contemporary molecular biology protocols. It also presents a microfluidic security flow that provides a high-level of confidence in the integrity of such protocols. In summary, this book creates a new research field as it bridges the technical skills gap between microfluidic systems and molecular biology protocols but it is viewed from the perspective of an electronic/systems engineer.

This volume contains the invited lectures presented during the NATO/ASI conducted in Pullman, Washington, July 9-18, 1989. This is the third in a series of NATO/ASIs on transport phenomena in porous media. The first two, which took place at Newark, Delaware in 1982 and 1985, are devoted to various topics related to the Fundamentals of Transport Processes in Porous Media. The contents of the books resulting from previous NATO/ASIs are given at the end of this book. Transport of extensive quantities such as mass of a fluid phase, mass of chemical species carried by a fluid phase, energy and electric charge in porous media, as encountered in a large variety of engineering disciplines, is an emerging interdisciplinary field. The groundwater flow, the simultaneous flow of gas, oil and water in petroleum reservoirs, the movement and accumulation of pollutants in the saturated and unsaturated subsurface zones, thermal energy storage in reservoirs, land subsidence in response to charges in overburden loads, or to pumping of fluids from underground formations, wave propagation in seismic investigations or as produced by earthquakes, chemical reactors, water flow through sand filters and the movement of fluids through kidneys, may serve as examples of fields in which the theory of transport in porous media is employed.
