Aerospace engineering faculty member Fabien Evrard received the W. R. Marshall award from the Institute for Liquid Atomization and Spray Systems for his paper, “Conservative two-phase flow simulations using piecewise-quadratic interface reconstructions.” The paper’s co-authors are Berend van Wachem, from the University of Magdeburg and Olivier Desjardins from Cornell University.
Current state-of-the-art methods to simulate fluid spray, such as what occurs in aerospace propulsion, are limited by their use of linear calculations to locally approximate the gas-liquid interface.
“This research addresses those limitations,” Evrard said. “We have developed new computational geometry tools that enable conservative, higher-order interface reconstructions, offering more detailed and reliable simulations of atomizing gas-liquid flows. While this has been achieved in two dimensions in the past, our work is a major step forward in bringing those capabilities to more practical, three-dimensional settings.”
Evrard earned his Ph.D. in mechanical engineering from Imperial College London in 2018, followed by a postdoctoral research position at the University of Magdeburg and a Marie Skłodowska-Curie postdoctoral fellowship at Cornell University. Evrard has authored or co-authored more than 40 publications. He was recently appointed as co-lead of the Computational and Modeling Technical Committee of ILASS-Americas.
