Накратко на български

Цифрови инструменти за симулация на впръскването на гориво в двигателите се разработват чрез нов математически модел. Това помага за създаването на по-ефективни системи, които да намалят разхода на гориво и вредните емисии от въглероден диоксид в транспорта.

Holistic Approach of Spray Injection through a Generalized Multi-phase Framework

HAoS-ITN network has developed a new generation of numerical tools that are available to both academic and non-academic sectors which can be utilized to design more advanced and efficient fuel injection systems and as a result, the fuel consumption and CO2 emissions from the transport sector would be reduced The work has been completed according to the Grant Agreement, fully respecting the overall project aim. The scientific outcomes of HAoS have been published in numerous peer-reviewed and highly esteemed journal papers and conference proceedings. In addition to the conducted research, the HAoS network has trained the ESRs on a range of unique scientific modules, that have broadened their perspectives in both research and classical engineering skills. Equally important, ESRs have been trained on a range of transferable skills. Last but not least, the ESRs have been engaged in numerous outreach activities, disseminating their work to relevant non-specialised communities that made the EU funding and the impact of the performed research visible to the general public.

Цел на проекта

Development of fuel injection equipment (FIE) able to reduce pollutant emissions from liquid-fueled transportation and power generation systems is a top industrial priority in order to meet the forthcoming EU 2020 emission legislations. However, design of new FIE is currently constrained by the incomplete physical understanding of complex micro-scale processes, such as in-nozzle cavitation, primary and secondary atomization. Unfortunately, today’s computing power does not allow for an all-scale analysis of these processes. The proposed program aims to develop a large eddy simulation (LES) CFD model that will account for the influence of unresolved sub-grid-scale (SGS) processes to engineering scales at affordable computing time scales. The bridging parameter between SGS and macro-scales flow processes is the surface area generation/destruction occurring during fuel atomisation; relevant SGS closure models will be developed through tailored experiments and DNS and will be implemented into the LES model predicting the macroscopic spray development as function of the in-nozzle flow and surrounding air conditions. Validation of the new simulation tool, currently missing from today’s state-of-the-art models, will be performed against new benchmark experimental data to be obtained as part of the programme, in addition to those provided by the industrial partners. This will demonstrate the applicability of the model as an engineering design tool suitable for IC engines, gas turbines, fuel burners and even rocket engine fuel injectors. The proposed research and training programme will be undertaken by 15ESRs funded by the EU and one ESR funded independently from an Australian partner; ESRs will be recruited/seconded by universities, research institutes and multinational fuel injection and combustion systems manufacturers that will represent in the best possible way the international, interdisciplinary and intersectoral requirements of the Marie Curie Action guidelines.
