Computational Modeling

Systems exhibiting complex, coupled physics such as multiphase flow devices  require computer simulations to capture their behavior in detail. These models are multiscale in nature, requiring detailed models of small systems to capture the complete physics and create coarse-grained models to capture the salient features of industrial-scale devices. In the Boyce group, we seek to develop accurate models at all levels, constantly working with experiments to validate models and uncover important physical mechanisms.

Magnetic Resonance Imaging (MRI)

MRI has long been used as a powerful tool for investigating the interior of the human body. The principles of MRI extend just as well to other opaque 3D systems, such as chemical reactors, geological flows and water purification devices. Since MRI is built upon the principles of nuclear magnetic resonance, it cannot only create 3D images, but also monitor chemical reactions, temperature, mass transport, flow and diffusion on a spatially resolved level.

Wasif Zia Joins Boyce Group as Newest Post Doctoral Research Scientist

Dr. rer. nat. Wasif Zia received a National Distinction before starting his doctorate at RWTH Aachen University, Germany, where he also co-authored a leading textbook on compact/mobile NMR devices (Compact NMR, De Gruyter Boston/Berlin 2014).

He holds the world record in the smallest permanent magnet based novel MR devices including single-sided, and closed Halbach-like geometries. He specializes in data acquisition techniques and MR methodologies to tackle low signal, high noise environments.

Collapse of a Bubble: CFD-DEM Study Published by the American Physical Society

The publication Collapse of a Bubble Injected Side-by-Side With Another Bubble into an Incipiently Fluidized Bed: A CFD-DEM Study was recently published by the American Physical Society.  This study used rapid magnetic resonance imaging to show how one bubble collapsed while the other bubble survived after the two bubbles were injected side-by-side into an incipiently fluidized bed.  The bubble that survived reached the surface of the fluidized bed.

Alireza Bordbar Joins Boyce Group as Newest PhD Student

Alireza Bordbar has recently joined the Boyce Group and is excited to embark upon a PhD research project focusing on multiphase flows using experimental and numerical techniques.  Alireza previously worked on numerical simulations of multiphase flows and microfluidics in Shiraz University in Iran, where he earned his master’s degree in mechanical engineering.
