In order to evaluate their potential usage in diesel engines, alternative fuels have to be analyzed at least in relation to: cetane number, density, viscosity, cloud point, flash point, cold filter plugging point, fuel corrosiveness, lubricity, water content, and fuel stability.
F.01 Acquisition of new practical knowledge, information and skills
COBISS.SI-ID: 19906326Summer school was organized by Kolektor Turboinstitut and University of Trieste at the end of European project ACCUSIM (People Programme (Marie Curie Action) of the European Union’s Seventh Framework Programme FPT/2007-2013/ under REA grant agreement n°612279), but some of the presented results were obtained also in the program P2 -0196. The main topics were: turbulence modelling, open code OpenFOAM, cavitation and design optimization. Summaries of the lectures were published in short proceedings. Besides 9 lectures, the school was attended by 20 students, 10 engineers and 7 researches from Slovenia and Italy. The summer school offered a unique opportunity for students and researchers as well as professionals, working in computational modeling of hydraulic machines, to participate in the knowledge transfer, provided in part from the side of academic researchers of the programme P2-0196 and the researchers from engineering company Kolektor Turboinštitut, which are also members of the P2-0196.
F.18 Transfer of new know-how to direct users (seminars, fora, conferences)
The energy utilization of municipal solid waste is possible with the appropriate integrated waste management system and utilization of appropriate technologies. In the process of development of a suitable WastetoEnergy technology, the application of advanced engineering computer simulation tools (CFD) should become standard for every R&D in WtE technology design. CFD can provide results, comparable to tests on full scale equipment, and can therefore significantly shorten the development time of WtE technolgies. The developed processes enable faster and more economical introduction of solid waste utilization technologies.
F.10 Improvements to an existing technological process or technology
COBISS.SI-ID: 16760854Products in the pharmaceutical industry are often sensitive to high temperature, because of biological and chemical changes in the material. Therefor the pharmaceutical industry uses lyophilizers in the manufacturing stage, which are responsible for the drying of the product under strong vacuum and low temperatures. For the optimization of the process a detailed resolution of the fluid flow is needed, which can be computed by the use of computational fluid dynamics (CFD). The latter codes were improved with special purpose computational tools, developed by the researchers of P2-1096, for solution of the drying inside the vials. The research was done in collaboration with the pharmaceutical company LEK, a part of Novartis. The research is currently still continuing with development of computer based determination of design space for laboratory and production scale lyophilizers.
F.10 Improvements to an existing technological process or technology
COBISS.SI-ID: 19401238The work was focused on the development of unique standard gas consumption profiles for the end gas consumers and the preparation of a method for the implementation of the developed profiles for forecasting and preliminary gas allocation. Four years of gas consumption (1.9.2009 - 31.5.2014) and temperature measurements were used to develop eight types of consumption profiles for 17 gas consumer groups, which were grouped according to their professional activity. As an alternative to the exponential, Gompertz or logistic model functions, frequently used in gas consumption model developments, the sigmoid model function is implemented and model constants for the eight types of profiles are developed based on the knowledge of the temperature independent portion of the gas consumption and separate treatment of workdays/weekends. Based on these profiles, a method was developed for the preliminary allocation of the gas consumption. The developed profiles and the gas consumption allocation method were validated on the available set of gas consumption data for the Slovenian gas market, proving the sigmoid model function based gas consumption allocation as an accurate and viable means of gas consumption forecasting. The work was done under the contrat with the Energy Agency of the Republic of Slovenia.
