Abstract
The program group is focused on in-depth understanding of physical phenomena in the intricately coupled multiphase systems that involve gas, liquid, solid and allotropic phases on different scales. The research methodology is based on connected experimental work, numerical modelling and simulation. The experimental work is performed in own laboratory facilities, domestic and foreign industry, medical facilities, and in close collaboration with large international research centres. The physical description of phenomena is based on combined continuum mechanics, cellular automata and phase-field formulation. Own laboratory equipment enables sophisticated experiments on the microfluidic scales and scales of the pilot industrial devices. The numerical simulations are based on our leading multiscale (properties-microstructure-macrostructure) and multi-physics (fluid mechanics, solid mechanics, chemical reactions, electromagnetic fields, ultrasound fields) models of the multiphase systems, solved by an entirely new generation of meshless methods, originally developed in our programme group. The physical modelling is complemented, replaced and/or tuned on the basis of artificial intelligence in cases where the physical models do not exist yet, are computationally too intensive or do not perform satisfactorily. The optimisation of multiphase systems is being established based on the evolutionary computing. The combination of self-developed software and access to domestic and foreign top high-performance computing facilities enable leading science and technology-oriented simulations. The newly gained knowledge is used in a broad spectrum of natural and technological systems; from the micro-fluidic devices to large steel ingots. The research forms an important contribution in understanding of the physiological processes, optimisation of different elements of the production process yield, topmost product perfection, and minimization of the environmental impact. They contribute to digitalization of the production and are fully integrated into the Industry 4.0 concept. Users of the program group's basic knowledge include large international research centres such as the ITER fusion program in France, the EuXFEL free electron laser in Germany, and the BELLE-II experiment in Japan. Applied research is related to high-tech pharmaceutical, biotechnology and metal-processing industry in Slovenia, global manufacturers of metallurgical equipment and global manufacturers of special types of steels. The program group is obtaining several high domestic and international awards and recognitions, and at the global level influences basic knowledge, design, and education in the interdisciplinary field of multiphase systems.
Significance for science
Research program belongs to the modern research area of modelling, simulation and optimisation of processes, materials and products, which plays an ever increasing role in international research - because of the impulses for inexpensive products with a large know-how input, for new materials, products and environmentally friendly technologies. Our research program is actively integrated in this research area by its basic and applied components. In the framework of our fundamental research, we are seeking new approaches in modelling of multiphase systems at coupled microscopic and macroscopic scales by using advanced meshless methods in combination with machine learning. We demonstrated first development and application of meshless methods to industrially relevant turbulent fluid flow problems, two-phase flow, coupled thermo-fluid-mechanics problems, problems with free surface and large deformation problems. We pioneered the first application of meshless methods in microstructure modelling with our original point automata method and adaptive parallel simulations. We demonstrated first through process model of aluminium and steel production based on artificial neural networks. The meshless boundary method of fundamental solutions has been developed for solid and fluid dynamics problems where the discretisation of the fictitious boundary is not needed any more. We have also developed a local form of this method, useful for calculating large problems, which was not possible before. We are also involved in the development of international test cases for Stefan problems and comparisons between numerical models and experiments. We have among others for the first time demonstrated discretisation independent results of macrosegregation as well as suggested first international test case for continuous casting of steel. The proposed research has a direct link to international research area (Europe, USA, Asia) through several international projects. International education, originating from the present program, results in the cooperation with universities abroad, and in the undergraduate and graduate modules of the Faculty of Mechanical Engineering. The program group leader and his team members have edited several special issues of top ranked journals with the research field of the program group. The program group is since 2020 additionally funded for experimental and computational development of new sample delivery systems in femtosecond crystallography; an important tool in COVID-19 pandemic related search for vaccines and drugs. We made game-changing results in development of double flow focusing nozzles (now used worldwide in free electron lasers and synchrotrons) in new types of converging-diverging nozzle outlet orifices and liquid micro-sheets. We have been the first who demonstrated the physically relevant and experimentally verified compressible flow simulations of the micro-jet breakup phenomena in such system by extensive use of high-performance computing. The scientific topics of the program group are consistent with the Horizon Europe research priorities: climate-neutral, green, and digitally advanced Europe.
Significance for the country
The proposed continuation of research program includes balanced basic and applied research spectra as well as concrete high-tech modernisations of systems, manufacturing processes, and products. The research is characterised by logical progression: almost all knowledge, developed in the framework of the previous oriented basic and precompetitive research, on which the proposed program is based, proved to found application in large research centres abroad and industrial application in Slovenia and worldwide, soon after development. The program group is actively collaborating with largest, most profitable and export -oriented metal-processing companies in Slovenia (which contribute about 1/3 of Slovenian GDP), such as IMPOL Slovenska Bistrica (continuous-, thin strip-, horizontal- and EM casting of aluminium alloys), METAL Ravne (casting of large steel ingots, electroslag remelting), Štore Steel (through process modelling), TALUM Kidričevo (implementation of nanoparticles in aluminium), HIDRIA Idrija (pressure die casting), Litostroj Power (development of new water turbines and auxiliary equipment). The listed examples demonstrate spin-offs of our basic project results which influence several tenths of million € savings each year and are undoubtedly important for Slovenia. The program group contributes to transformation of this traditionally resource- and energy-intensive industry to knowledge based digitalized Industry 4.0. The top end knowledge, gained within the proposed program, fosters the collaboration and export of Slovenian knowledge to global multinational steel equipment process industry (DANIELI from Italy) and to the largest world steel producers (Xiwang Special Steel Company, China). This provides new research jobs in Slovenia and strengthens the international reputation of Slovenian science. The program group provides simulation support to the high-tech company BIA Separations, a global leader in the development of monolithic technology and the only manufacturer of monolithic chromatographic columns for the production, purification and analysis of major biological molecules such as viruses, plasmid DNA, exosomes, antibodies, bacteriophages, etc. It contributes to the development of mixing systems in LEK/NOVARTIS company and process equipment for coating of particles in BRINOX company (patented in Europe, USA, Eurasia and India). Our knowledge is involved in most advanced research programs like German Helmholtz Association in the field of modelling of development of new sample delivery systems for femtosecond crystallography, in the French CEA in the field of analysis of the influence of plasma on the thermal load of ITER tokamak linings. We have also participated in simulations for mitigation of thermal loads on detectors in the BELLE-II experiment in Japan. These achievements demonstrate that the research group contributes to the development of researchers which are able to participate in the most demanding scientific projects worldwide. Additionally, the proposed research strengthens Slovenian scientific and cultural heritage and national identity and has to be at home in Slovenia prior to anywhere else! Jožef Stefan (1835-1893) was among the first who made the analytical foundations for liquid-solid processes. In honour of our great scientist, such processes got the name Stefan problems. This program copes with the field of Stefan problems. The vision of the programme group is to maintain the achieved leading role in simulations of multiphase systems based on meshless numerical methods and to support the Slovenian and global industry in establishment of competitive technological procedures and products in an economic and environmentally friendly way. In addition, the vision of the programme group presents also involvement of topmost education in the field of experimentation, modelling and simulation of materials and processes as well as use of high-performance computing in doing so. The justifiable expectation of the program group in the next period is a proportional increase of the state funding, since the program group has grown by more than 3x in the past five years, its scientific results have increased by more than 5x, and doctoral education by more than 10x.
