CBE Seminar: Dr. Yaofa Li, Mechanical & Industrial Engineering, MSU
- Thursday, September 2, 2021 from 4:10pm to 5:00pm
Join us as we kick-off our Fall 2021 Seminar Series! We are pleased to host Dr. Yaofa Li, assistant professor in MSU’s Dept. of Mechanical and Industrial Engineering. Dr. Li’s research focuses on developing novel, experimental studies of thermal-fluid problems primarily at small scales with broad applications in energy, water, and the environment. Read about Dr. Li’s research lab M-LEFT
Abstract: Complex microscale flows and transport, such as multiphase flow in porous media and free surface flows are central to a range of applications in the heat and energy sector. These applications include but not limited to evaporative cooling, CO2 capture and storage (CCS), fuel cells and enhance oil recovery (EOR). Understanding the underlying physics of these complex flows at microscale is required for understanding, guiding and improving those real operations. Recent advances in micro/nanofluidics and laser-based flow diagnostics such as microscopic particle image velocimetry (micro-PIV) have provided great experimental tools for such purpose. In this talk, I will highlight the use of microfluidics and micro-PIV in the studies of a couple of fundamental flow problems relevant to microscale heat transfer and clean energy.
In the first part of my talk, I will present the multiphase flow of supercritical CO2 and water in a 2D porous micromodel. The work is primarily motivated by the safe and secure CO2 capture and storage (CCS) for the purpose of greenhouse gas mitigation. Nevertheless, the relevance of this work goes beyond CCS, shedding light into problems such as fuel cells, enhanced oil recovery (EOR) and groundwater remediation. By taking advantage of the state-of-the-art micro-PIV, a few previously ignored phenomena are re-assessed for the first time, which challenges traditional predictive models and meanwhile provides new insights for the development of new advanced models. In the second part, I will briefly talk about a couple of ongoing projects in my group, including the design of a microfluidic pressure sensor for capillary pressure measurement, and the quantification of mineral dissolution in porous media. Through these projects, I will focus on the demonstration of the techniques and our capabilities, with the purpose of inspiring new research ideas and fostering new collaborations.
