Dr J. Li's research focuses on the investigation of multiphase flows using state of the art numerical methods. Multiphase flows are ubiquitous in technology applications. Examples include inkjet printing, cavitation (formation of vapour bubbles in sufficient low pressure regions) and spray (combustion of liquid fuels in droplet forms). Multiphase flows are in general highly nonlinear and analytically intractable. Our present state of knowledge in this area is far from complete and ripe for further research.
Dr Li's expertise lies on interface tracking methods and the modelling of the physical phenomena on the interface. He is among the early pioneers who invented independently a second order Volume of Fluid (VOF) method, a very popular interface tracking method nowadays. He has also developed a highly accurate and efficient adaptive mesh method which is tailed for the study of moving boundary problems. He has used his methods to investigate important phenomena involved in multiphase flows, including viscoelasticity, surface tension, surfactant, contact line, triplet point, rarefied gas dynamics, droplet collisions and droplet impact on solid walls. Dr. Li's work in the filed of multiphase flows is well recognized: his work was cited more than 1000 times and his h-index is 17.
