Research
Broadly speaking, I am interested in complex fluid flow phenomena. As complex I understand flows where confounding aspects are relevant, such as chemical reactions and heat transfer, transitional Knudsen flows, electromagnetic fields, acoustic phenomena, interacting shocks, boundary layer separation, turbulence, among others. A poster child problem that illustrates many of these features is atmospheric entry. Upon entry, a vehicle at hypersonic speeds will be subject to a fluid flow characterized by species dissociation and ionisation, with ensuing electromagnetic fields, high heat transfer rates (including radiation), varying Knudsen numbers (high to low), turbulent boundary layers, surface reactions and ablation, etc. I believe this to be the frontier of the engineering discipline. The simulation of the multiphysyical nature of these problems demands simultaneous solution of a myriad of equations, and in general require high temporal and spatial resolution, with codes that typically are run on HPC platforms.
Below is a list of current projects:
- Supercomputer Simulation and Big Data Analysis Of Environmental Noise from Aircraft and Mechanisms of its Generation (SONG)
- Gas Kinetic Method
- Quantum algorithms in CFD
- Low subsonic wind tunnel
