Pavanakumar Mohanamuraly
Early Stage Researcher 3 at Queen Mary University of London
Brief:
I am an aerospace engineer with a wide range of experience, from setting up supercomputers to intellectual property and business analytics. I have been associated with Airbus Group and several Aerospace Labs in India. I have a masters degree in Aerospace Engineering with minor in Computational Science from Pennsylvania State University, University Park, USA, where I was a graduate research assistant in the Vertical Lift Research Center of Excellence (VLRCOE).
My main areas of expertise are Computational Fluid Dynamics, Aeroacoustics, and High performance parallel scientific code development. Intellectual property and data analytics are some new areas I have developed a deep interest in.
My IODA research theme revolves around "Uncertainty analysis and robust shape optimisation in the presence of uncertainties". This has a healthy mix of optimisation, CFD, and data analytics. You can find more information about my work in the research section.
The Marie Curie IODA fellowship has enabled me to return back to grad-school life and make me feel younger. This has given me the opportunity to network with a large circle of researchers and industry partners, which would otherwise be inaccessible.
Objectives:
1) Robust large mesh deformation via elastic formulation, harmonic coordinates and optimisation-based smoothing. Automatic remeshing steps with local repair or global remeshing
2) Multi-objective adjoint solvers using vector AD, robust optimisation using second moment and inexpensive Monte Carlo techniques
3) Implementation in in-house flow solver
Work packages:
WP 2: CAD-free design parametrisation
WP 5: Constrained optimisation
WP 6: Integration into industrial workflows
