Computational fluid dynamics (CFD) has emerged as a powerful tool for understanding fluid mechanics in multiphase reactors, widely used in the chemical, petroleum, mining, food, beverage, and pharmaceutical industries. CFD techniques are essential in the design process as it provides an inexpensive and efficient way to design and optimize the system. More importantly, CFD can provide detailed spatiotemporal flow information that is crucial to gain insights into the nature and underlying mechanisms of the flows. We have successfully applied to various length scale problems and predicted flow behavior.
Fluidized beds are one of the most versatile chemical reactor designs, with applications in oil refining, power generation, pharmaceutical manufacturing, and mineral processing. In many cases, they are the heart of these processes (e.g., FCCU, fluid cokers, fluidized bed combustors). The complexity of these reactors also makes them fertile ground for academic research. The most fascinating thing about fluidization is the transformation it brings to a static fixed bed of particles contained in a vessel.
Explore the captivating realm of multiphase flow and slurry transport through a multidisciplinary approach combining experimental, computational fluid dynamics (CFD), and CFD coupled with population balance modeling (CFD-PBM) studies. This research category delves into the complexities of multiphase systems, investigating their behavior, dynamics, and hydrodynamic characteristics. Complementing this, CFD techniques provide insights into flow patterns, particle trajectories, and fluid behavior, while the integration of PBM in CFD simulations enables an accurate representation of particle-related phenomena. Our research aims to optimize industrial applications by advancing the understanding of multiphase flow and slurry transport.
Our research focuses on the dynamic behavior of both Newtonian and non-Newtonian fluids at the microscale. Using advanced experimental techniques and numerical modeling, we investigate the processes of droplet formation, coalescence, breakup, and bubble generation. Leveraging the unique capabilities of microfluidic platforms, we gain profound insights into interfacial phenomena, rheological properties, and flow instabilities exhibited by droplets and bubbles.
