FLUIDODINAMICA 3D

I processi di combustione sono presenti in diversi settori industriali, dal civile-domestico alla generazione di energia, dall'industria alimentare a quella chimica e petrolchimica, dai trasporti fino a settori fortemente energivori quali l'industria del cemento, del vetro e della ceramica. Le applicazioni sono molto differenti fra di loro per potenza, per tipologia di combustibile e per sistema di combustione.

The Kargi Project that consists of the construction of the second major hydroelectric power station in Turkey, will be completed in the second half of 2013 with the direct involvement of expertise, resources and technologies coming from all over Europe. The power station located about 200 km northeast of Ankara, will take advantage of a geodetic head, partially natural and partially artificial, of about 80m provided by the Kizilirmak Basin.

The subject of analysis is a vane oil pump for truck applications. This product represents new generation oil pump in automotive industry thanks to the possibility to reduce the displacement at high engine speed for fuel save consumption.

The development of robust design strategies coupled with detailed simulation models requires the introduction of advanced algorithms and computing resource management tools. On the algorithmic side, we explore the use of simplex-based stochastic collocation methods to characterize uncertainties, and multi-objective genetic algorithms to optimize a large-scale, three-dimensional geometry using a very large number of CFD simulations on HPC clusters.

The so-called trapped vortex technology can potentially offer several advantages for gas turbine burners. In the systems experimented with so far, this technology is mainly limited to the pilot part of the whole burner. The aim of the work we present here, is to design a combustion chamber completely based on the trapped vortex principle, investigating the possibility to establish a diluted combustion regime, in case of syngas as fuel.

The Westinghouse AP1000 nuclear reactor design is a pressurized water reactor with a power rating of 3415 MWt and an electrical output of at least 1000 MWe. The AP1000 design contains a variety of engineering and operational improvements providing additional safety margins and addresses the U.S. NRC severe accident, safety goal, and standardization policy statements.
