I am currently working at Exa Corporation Munich as a Team Lead for Aero-acoustics. My responsibilities involve: • Managing the Aero-Acoustics field team in Munich (5 FTE) • Aeroacoustic, aerodynamic and thermodynamic projects in Western and Central Europe, and Asia • Managing Research and Developement aeroacoustics projects with leading European car manufacturers • Driving deployment […]
I am currently working on Windnoise applications for Exa corporation, using the low dissipation high performance Lattice Boltzmann approach to solving fluid flow around ground transportation vehicles. I have been involved in operations in the DACH region, as well as the rest of Europe and some parts of Asia, working on consultancy projects for standard […]
Whilst putting the finishing touches on my thesis, I have started working with the OSCILOS team on developing non-linear flame models used in this open source code for simulating combustion instability. You can find more details about OSCILOS here. The source code will be kept up to date on GitHub here. Contributions welcome.
I’ve played around a bit with Tikz, and I consider it to be hands down the most latex friendly tool for inputting images in Latex documents. I have also been having issues with putting figures from Matlab into my Latex documents. Up until now, I was saving them as eps, then using \includefigure to add them […]
There are some speed optimisations which are obvious in matlab: always pre-allocate your array use implicit vector notation if possible don’t set loop indexes or tests which require the creation of large arrays every loop iteration But one of the ones that was less obvious, at least to me, was the concept in Matlab of […]
The paper entitled “The effect of a laminar moving flame front on thermoacoustic oscillations of an anchored ducted V-flame” has now been accepted by the Combustion Science and Technology journal and is pending publication.
The hydrodynamics modelling model is capable of capturing the same oscillatory phenomenon as shown in Assier 2013. In addition to that, decreasing the laminar burning velocity leads to anchoring of the flame and reduction in growth rate and limit cycle amplitude.
The code currently under development for the modelling of hydrodynamic effects is being rewritten. It has suffered from the results of concurrent coding and development, and therefore needs a bit of restructuring before producing results for publication.
Part of my work on the modelling of hydrodynamic effects in anchored flame combustion instabilities requires the treatment of non periodic signals with Fourier series. This is successfully performed by extending the signal over a virtual domain, and ensuring that it remains periodic within this extended domain. This is a common method for steady problems. […]
The method of characteristics for modelling plane wave acoustics requires the calculation of pressure waves between time steps. this is done using linear interpolation. This linear interpolation is responsible for an increase in the error obtained when computing pressure and velocity values within the duct. It can be avoided in certain cases. Choosing a specific […]
