Department Head and Charles A. Miller, Jr. Distinguished Professor
Computations of multiphase flows. Direct numerical simulations of complex multiphase flows including heat transfer, boiling, cavitation, solidification, surfactants, and reactions. Applications to turbulent bubbly flows, atomization, additive manufacturing, and other problems. Numerical methods for tracking sharp fluid interfaces. Averaged and reduced order models of multiphase flows. Multiscale approaches to capture small-scales in multiphase flows.
Gretar Tryggvason is the Charles A. Miller, Jr. Distinguished Professor in Mechanical Engineering and head of the Department of Mechanical Engineering at Johns Hopkins University. Tryggvason came to Johns Hopkins from the University of Notre Dame, where he was the Viola D. Hank Professor and chair of the Department of Aerospace and Mechanical Engineering (2010 – 2017). From 2002 to 2015, he served as Editor-in-chief of the Journal of Computational Physics. Tryggvason is widely recognized for his contributions to computational fluid dynamics, including to the development of methods for computations of multiphase flows, as well as for pioneering direct numerical simulations of such flows. Tryggvason received his PhD from Brown University in 1985.
