Expertise

Professor Yu’s research field is in computational fluid dynamics in general with expertise on kinetic theory based lattice Boltzmann method to model and simulate complex flows including turbulence. Her current research focus is to synergistically combine LBM with GPU technology to develop efficient and unique approaches to simulate and visualize real time flow dynamics and flow-wall structure interactions in healthy or diseased human organs (aorta, heart ventricle, ureter, carotid artery, etc. ) segmented from radiological scanning.

Interests

1. Lattice Boltzmann method for flow-structure interactions in human organs 2. Lattice Boltzmann method for imaging, e.g. segmentation, de-noising, lightning 3. Turbulence control through PT symmetry 4. Bubble dynamics in reactive multiphase flow
