Kyongmin Yeo

 Welcome !

I am a graduate student at the Division of Applied Mathematics, Brown University.

During my master study, I worked on the Lagrangian characteristics of turbulent flows and now my research topic is low-Reynolds-number hydrodynamics, particularly, numerical simulation of concentrated suspensions. My research interests are both high-Reynolds-number turbulent and low-Reynolds-number creeping flows. For the numerical simulations, I made 3-D Navier-Stokes and Stokes solvers employing high-order numerical schemes, such as the spectral and spectral element methods. Old Navier-Stokes solvers for isotropic turbulent flows with a high order particle tracking scheme are written in Fortran90 with OpenMP or MPI. A new Navier-Stokes solver in cylindrical coordinates and Stokes solver for a channel flow is in C++ with MPI. I am planning to make them available soon.

My advisor is Prof. Martin Maxey who is one of the nicest people I have ever known!
