This years Combura conference will be held on the 10th of october at our regular spot Kontakt der Kontinenten. The NVV members meeting will take place on 9th of October at the same place as Combura. Please save the date in your calendar and we hope to see you there.



Support Metalcycles project

The NVV is proud to announce that it is supporting the MetalCycles research programme that has been submitted to perspectief call from the NWO domain TTW. 

Project summary:

In the search for low/no CO2-emitting energy applications, the research program MetalCycles will develop metal fuel energy applications. Metal fuels have very high energy densities, comparable to fossil fuels. The combustion and regeneration of metal (a.o. iron, zinc) will be investigated in order to develop a zero-carbon emitting cyclic energy generating process. Metal oxide regeneration will be performed using renewable resources, like wind, solar PV and hydropower. The technology will be applicable in Combined Heat Power (CHP)-systems, transport (tanker-ships, truck, car), hydrogen production and large-scale energy generation, making it possible to use existing power plant infrastructure. To contribute to the circular economy, the cycles will be initiated by the use of metal waste for which sustainable and selective pre-treatment methods will be developed. The economics, sustainability and societal impact in relation to the implementation of the technology in the various sectors mentioned will be an element of the program as well. From an economic point of view implementation of a novel technology allows new market opportunities, especially in CHP and transport development. From a societal point of view safety, health and environmental issues in addition to critical resourcing (e.g. food/materials by transport) will be impacted.

NVV sponsored research: LES simulation of non reacting flow in a GT Combustor

One of the NVV sponsored projects has resulted in a publication in Flow, Turbulence and Combustion.

Combustion Award 2017

At the annual combustion conference Combura the combustion award 2017 has been award to the student with the best master thesis in the field of combustion. This year the price has been awarded to Ambrus Both for his work: RANS-FGM simulation of a n-heptane spray flame in OpenFOAM.

This year we’ve received submissions of students from Eindhoven en Delft. Most of the thesis were focuses on diesel engines. Varying from the validation of simple, fast models for the predication of NOx based on engine parameters to the effect of injection strategy on particulate matter emissions. Demonstrating that even such a well-known and relatively old technology as diesel combustion is still very relevant and optimization is still possible reducing the effects theses engines have on our environment.

In the end the award was given to a thesis which describes an alternative strategy to model liquid flames. In this work he introduces a novel way of coupling the properties of the droplets to the other variables in the CFD simulation. Where in previous models the properties needed to be stored in a look-up table, the properties are now directly linked to the underlying FGM variables. This results in a very lightweight approach. This is another important step in improving the results of FGM simulations with liquid fuels.

Ambrus described the complex theory behind FGM simulations and his liquid combustion model very clearly. Making it the perfect basis for further development.
