Aerothermodynamics<img alt="" src="" style="BORDER:0px solid;" /><p>​The general goal of CIRA, in the field of Aerothermodynamics, is the development of tools and competences for the simulation and the analysis of high-energy flows. Therefore, the supersonic and hypersonic flows typical of the re-entry phase of a hypersonic vehicle [IXV.jpg] or of a capsule are studied, both on earth atmosphere or on other planets, along with the aerodynamics of a launcher at high velocity and ramjet/scramjet propelled space planes [HEXAFLY.jpg]. The use of computational fluid dynamics tools, both in flight and wind tunnel conditions, is fundamental in the field of aerothermodynamics to correlate the real flight conditions with the on-ground experiments [SWBLI.jpg]; actually a proper use of CFD tools allows on one side to optimize the design of ground tests and to correctly interpret the wind tunnel data, and on the other side to extrapolate the experimental data to the flight.
