About me

I am Harshith Gowrachari, a Postdoctoral Researcher at ONERA - The French Aerospace Lab, Toulouse, France.

I currently work on the EU-funded Impact Monitor 2 project with DLR and NLR, contributing to the environmental impact assessment of aviation. I perform Large Eddy Simulations (LES) of aircraft pollutant dispersion with online chemistry at the local airport level, using the Meso-NH atmospheric model. Further, I develop reduced order and multi-fidelity models that enable fast evaluation of the many scenarios required for impact assessment.

I am the developer and maintainer of miiPy, an open-source Python library for data-driven system identification, interpolatory model reduction, and operator inference.

Research Interests

• Computational fluid dynamics: reactive and multiphase flows, heat transfer, aerodynamics, and aeroacoustics
• Reduced order modelling: projection-based, data-driven, and nonlinear methods, especially for advection-dominated problems
• Numerical methods: finite volume, finite element, and finite difference methods for PDEs
• Applications: aerospace, metallurgical processes, energy, and, more recently, atmospheric physics
