naslovnica_Kuhljevi_dnevi_2015_4

Every year, the Slovene association for Mechanics (Slovensko društvo za mehaniko) organizes conference Kuhljevi dnevi (Kuhelj memorial conference), which honors the life and work of Slovene scientist Anton Kuhelj. This year the conference was in Moravske Toplice from 24th to 25th of September.

Dragica Jošt attended the conference and presented the paper:

Dragica Jošt  and Aljaž Škerlavaj attended ANSYS` Convergence Conference on 27th May 2015 in Ljubljana.

ACCUSIM group participated with the presentation:

Recent improvements of performance prediction by CFD for all types of water turbines

Authors: D Jošt, A Škerlavaj, M Morgut, E Nobile

Improvement of performance prediction by transient simulations and advanced turbulence models for Francis, Kaplan, bulb and Pelton turbines was presented.

Workshop FRANCIS-99

The Norwegian University of Science and Technology (NTNU), Norway, and Luleå University of Technology (LTU), Sweden, announced three workshops for Francis turbines. The goal of the first one was to determine the state-of-the-art of numerical predictions for steady operating conditions. The second and the third workshop will be focused on transient operation of turbines and fluid-structure interaction, respectively. In all workshops, a high-head Francis turbine model (Tokke model) will be employed as a reference test case. The model was designed and experimentally measured at Water Power Laboratory at NTNU.

Aljaž Škerlavaj and Mitja Morgut attended Workshop FRANCIS-99 in Trondheim, Norway. ACCUSIM group participated with the paper:

Numerical simulation of flow in a high head Francis turbine with prediction of efficiency, rotor stator interaction and vortex structures in the draft tube

Authors: D Jošt, A Škerlavaj, M Morgut, P Mežnar and E Nobile

TURBOINŠTITUT

From its founding on 28 June 1948, when the Yugoslav federal government established a strategic centre for scientific and industrial research, Turboinštitut has grown to become an integral part of hydraulic machine development in this region. It has grown in a country with a long-standing tradition of water turbine design and production (from the mid-19th century). Being an independent institute, without any ownership ties with any turbine or pump producers from its founding to this day, the Institute has been a valuable basic resource for turbines, pumps and ventilator production for many manufacturers.

For Turboinštitut (TI for brevity), who is present on the world market as a developer and even manufacturer of small hydro-machinery (up to 20 MW), it is very important to stay in touch with the latest technology, research and design in its field. Therefore, TI is not only following the trends, but represents a state-of-the-art player in research and design on the global scale. In 2008, TI bought a supercomputer with 2048 computer cores – at that time the most powerful supercomputer in South Eastern Europe. The new infrastructure allowed TI to explore the possibilities how to draw the numerical simulations near the experimental measurements. In 2013 two employees have finished their PhD study, which means that almost all employees in the BRE department of TI are in possession of a PhD degree (either of mathematics, physics or mechanical engineering). The latter indicates the importance of knowledge to TI.

Although the TI is already performing research in cavitation and in other areas, the Marie Curie IAPP call is a unique opportunity, both for TI and its researchers, to acquire the appropriate knowledge much faster than would be possible by standard research (and thus to gain the needed competitive advantage on world markets). In addition, TI and its researchers would establish strong connections with University of Trieste, which is performing more fundamental scientific research on a similar field of engineering.
