Rubino, A. (author), Pini, M. (author), Kosec, M. (author), Vitale, S. (author), Colonna, Piero (author)Fast and accurate computation of thermo-physical properties is essential in computationally expensive simulations involving fluid flows that significantly depart from the ideal gas or ideal liquid behavior. A look-up table algorithm based on unstructured grids is proposed and applied to non-ideal compressible fluid dynamics simulations. The...journal article 2018

Pini, M. (author), de Servi, C.M. (author), Burigana, M. (author), Bahamonde, Juan S. (author), Rubino, A. (author), Vitale, S. (author), Colonna, Piero (author)High temperature Organic Rankine Cycles power systems of low power capacity, i.e. 3-50 kW<sub>e</sub>, are receiving recognition for distributed and mobile energy generation applications. For this type of power plants, it is customary to adopt a radial-turbine as prime mover, essentially for their ability to cope with very large volumetric...conference paper 2017

Rubino, A. (author), Pini, M. (author), Colonna, Piero (author)Currently, turbomachinery design optimization methodologies are mainly restricted to steady state approaches, due to the high computational cost associated with time-accurate shape optimization algorithms. However, the possibility to include unsteady effects in turbomachinery optimization can significantly increase the level of accuracy of...conference paper 2017
