Gretar Tryggvason

Gretar Tryggvason is Department Head of "Mechanical Engineering" and Charles A. Miller Jr. Distinguished Professor at "Johns Hopkins University". He is known for developing the "front tracking method" to simulate multiphase flows and free surface flows. Tryggvason was the Editor-in-Chief of "Journal of Computational Physics" from 2002–2015.
Area of research.
Tryggvason has been a leading worker computational fluid dynamics and numerical methods. He is well known for his research on numerical simulations of vortex flows, multiphase flows, free surface flows, and flows with phase changes. For simulating multiphase flows, he and his co-workers have developed a front tracking method that incorporates an unstructured, moving grid within an underlying Eulerian grid.
