Alberto Guardone gives an overview of NICFD capabilities of SU2 at the 1st SU2 Developers meeting in Delft, 5-6 of September 2016. In the slide, the latest TROVA results provide the first-ever validation of a CFD solver for non-ideal flows.
All presentations can be downloaded following the embedded links in the agenda http://su2.stanford.edu/documents/SU2_Dev_Meeting_Agenda_20160905.pdf

Next Monday, the 5th of September, the most active development teams from around the world will join in Delft for the 1st Annual SU2 Developers Meeting. Giulio and Alberto will give a presentation about NICFD at 9.35 (CEST) and will take part to the two-day meeting for core developers.
Join us (in-person or virtually) and register by following the link on the SU2 home page (http://su2.stanford.edu).

Any student and researcher working in the field of ORC technology can apply to the research scholarships. The scholarships cover travel and accommodation related to short-term research projects of 3–6 months. The grants are 3.000–10.000 $ depending on project duration and location of the hosting institution. More details can be found on the KCORC website:
The third call is open until 30th September 2016.

Politecnico di Milano keeps investing in the CREA laboratory: construction works of the new building specifically designed to host the TROVA test-rig are currently under way at Campus Bovisa La Masa, Milano.

The first measurements using Laser Doppler Velocimetry are currently being carried out @TROVA. These are the first-ever velocity measurements within a non-ideal compressible-fluid flows in the close proximity of the liquid-vapour saturation curve. The flow seeding required the design and construction of a the pressurised seeding apparatus shown in the picture.

Shocks, turbulence and interactions in non-ideal and dense gases
Dr. Emile Touber, Imperial College
Abstract: Dense gases are characterised by molecules featuring large numbers of active degrees of freedom (quantified by the Cv/R ratio). The isentropes in such gases have the distinct property of following rather closely the isotherms (the two become identical in the limit of Cv/R going to infinity). Near the liquid-vapour critical point, this makes the isentropes very shallow and possibly concave (in the pressure-specific volume diagram). Whilst shallow isentropes are desirable when designing expanders (i.e. a large specific-volume increase may be achieved for virtually no pressure drop), could such extreme compressibility effects modify turbulence in a profound manner? This talk will discuss two particularly interesting aspects: (i) shock-refraction properties (i.e. the way a shock can redistribute the energy of incoming perturbations), (ii) the energy transfers in homogeneous turbulence (i.e. particularly the work done by the unsteady pressure force). In both cases we will show that non-convex isentropes are extremely influential in letting both the shock and the turbulence redistribute any supply of turbulence kinetic energy in ways which are simply not observable in ideal gases.
