Research Interests

• ASCI

The goal of the ASCI project at Stanford is to perform a detailed numerical simulation of a jet engine. I work on the multiblock flow solver TFLO, which solves the Reynolds Average Navier-Stokes (RANS) equations. TFLO is used to compute the flow field in the compressor and the turbine. Currently I am implementing some new nonlinear multigrid smoothers to speed up the convergence. An important problem to be tackled is to minimize the convergence degradation due to the parallelization. Furthermore low Mach number preconditioning needs to be implemented in the near future.

• Unstructured Grids

Unstructured grids are in principle well suited for automatization and therefore they offer great potential for design optimization. However, despite many efforts in the last decade, the discretization techniques for unstructured grids are still not as accurate and efficient as their structured grid counterparts, especially for the high Reynolds number Navier-Stokes equations the aerospace community is interested in. I am looking at several multigrid techniques suited for unstructured meshes and I intend to generalize the structured grid smoothers to unstructured grids.
