Significance for science
Neural network applications will be extended and adapted to the complex steam plants with the aim to optimize its energetic effectiveness. Research of the neural network application to rise RAM (Reliability Availability and Maintainability) index, disposability and reliability of classic steam plants. Development of models to assess savings in primary energy in polygeneration power systems, to acquire data bases for LCA studies, oriented innovative research work for continuous exploitation of biomass, collection and storage of carbon dioxide, as well as reduction of harmful emissions from exhaust gases will form the base and boundary conditions for basic research that enable design and construction of systems for gasification of the biomass. On the other hand biomass enables production of high caloric combustion gases. Further studies of technological solutions for hydrogen extraction process will be possible, as well as application of hydrogen in fuel cells for stationary and mobile applications. A special new area will be opened in the area of projecting alternative cogeneration hybrid systems based on fuel cells. Turbine machines are well understood and in wide spread use. For research in this filed the innovative approach is therefore essential. This is possible with relatively small and simple construction changes, which change aerodynamic and hydrodynamic properties of turbine machines, and which also increase the efficiency. Beside this, in the field of cavitation in water turbine machines, local thermal effects of cavitation, because of complexity of measurements and high price of measurement equipment, are until now not much investigated. They are in some respects essential for modeling of various engineering applications. Similarly, cavitation erosion is not well enough understood, although there were many studies performed. This limits the understanding of erosion mechanism and in this respect also reduces the possibility of further improvement of hydraulic machines. Research in the area of simulation model for modeling thermodynamic, fluid mechanics and power flow processes will contribute to basic and applied scientific knowledge as well as provide guidelines for innovative technical solutions. Basic research would be conducted towards: analyzing interactions of time scales for modeling the processes in components in terms of numerical stability and consistency of the results, analyzing influences of schemes for solving differential equations in terms of accuracy and CPU requirements, and optimizing complexity of gas properties models in terms of trade-off between accuracy of the results and CPU requirements. This research is performed in collaboration with the AVL List form Austria with the objective of developing first professional predictive real-time simulation model for ICEs, which confirms scientific relevance and timeliness of the research. Results of the research would be implemented also in our own source codes aimed at research in sustainable transport. For technology of mineral wool production the week part nowadays is the connection between mechanisms of fiberisation and integral process parameters, but has very significant impact on final quality of the product. Knowledge of fenomenological relations among the above-mentioned variables of integral process parameters will enable increased influence on final product quality. For risk assessment we will introduce new tools, among them CFD and new databases. Beside this the transfer from risk assessment will be transferred to microstructure in the field of gas transport in pipelines and knowledge of distribution of pipeline networks in closed industrial areas.
Significance for the country
Optimization of power plants, polygeneration and gasification of biomass form the base of the appropriate official European policy (Regulations FP7) and is also the official strategic orientation of the Republic of Slovenia. Republic of Slovenia confirmed in the "Resolution on the national energetic research and development program", the Kyoto agreement and its obligations for reduction of greenhouse gas emissions from the power plants that amount to 40% of all emissions in Slovenia. The main goal is to reduce specific emissions by the introduction of new or renewed - optimized technologies. Transition to renewable energetic sources opens a lot of relevant questions and introduces new challenges for research teams and national economy. Proposed program anticipates development of new research workers in R&D departments of the Slovenian industry and on different levels of education. In the mean time the academic sphere intensively joined research projects of the industry and cooperates when new modern education programs were offered. Exploitation of renewable energy sources in the field of water turbines and improvement of characteristics of turbine machines with hollow blades represent a scientific and economic opportunity. Development of such machines is compliant with European and worldwide scientific trends, EU research programmes and above mentioned regulations. For the market such machines, when manufactured by Slovenian industrial partners, which have in the past established close contacts with the programme group, represent increased competitive position of Slovenian companies. Research of cavitation in turbine machines and on profiles in cavitation tunnel, performed in last years, have made possible to establish close relations with research centers in France and Germany. Proposed common studies of cavitation (applied EU and bilateral projects) will answer some key questions, which will enable further research of technology in will reduce the operational costs. Connections among research groups will enable also knowledge transfer and education of young researchers.In-line with Kyoto protocol and Göteborg agenda, EU has launched the strategy for reducing CO2 emissions of light-duty vehicles to a level of 120 g/km in 2012 and corresponding emission reduction for light-commercial vehicles and heavy-duty vehicles. Additional reduction to 95 g/km should be feasible for light-duty vehicles in 2020. It is generally accepted that internal combustion engines would be the main propulsors in the addressed time frame. Therefore research towards environmental sustainable powertrains and vehicles is necessity. Research conducted towards sustainable transport has immense environmental and social impact, whereas our research group is also actively collaborating with domestic and foreign industry partners adding also an economic impact.Risk assessment of gas pipeline network in Slovenia is new, and in Europe this activity is very young and propulsive with high added value. We envision here possibility of new technology breakthroughs, and this enable us equivalent presence in European market with possibility of marketing of services.Results in the field of mineral wool in the past programme period have established the group as one of the leaders in the research in the field of mineral wool production in the central Europe. With development of phenomenological relations of mineral wool formation the influence of the group will be spread to other regions also. Such trends were shown also in the near past.
