Taracchini","doi":"10.1393/NCC/I2017-17122-6","DOIUrl":"https://doi.org/10.1393/NCC/I2017-17122-6","url":null,"abstract":"During its first observing run (O1), the Advanced Laser Interferometer Gravitational wave Observatory (LIGO) detected gravitational waves (GWs) emitted by the coalescence of two binary black holes (BBHs), GW150914 and GW151226 [1, 2]. A third candidate event, LVT151012, was also recorded [3], but with not high enough statistical significance to claim a detection. These discoveries opened the possibility of observing and probing the most extreme astrophysical objects in the Universe. These first detections and their detailed characterization represent the culmination of more than a decade of synergy between analytical relativity, numerical relativity (NR) and data analysis. The problem of describing the GW signal generated by a pair of BHs that (quasicircularly) orbit each other and eventually merge into a single BH is challenging because of the different dynamical regimes that this process spans. When the binary is wide —say, as compared to the BH horizons— the component objects move at orbital speeds (in the center-of-mass frame) that are small with respect to the speed of light. During this phase of the coalescence, the post-Newtonian (PN) (i.e., slow-motion and weak-field) approximation to general relativity can be employed to model the orbital dynamics and the associated GW emission (see, e.g., ref. [4] for an extensive review of the current status of PN theory applied to the two-body problem). As the BHs spiral in, plunge and eventually merge, their orbital motion becomes more relativistic and the GW energy flux is stronger. NR techniques are required to obtain highly-accurate waveforms during this stage of the process. State-of-the-art codes can now accurately evolve BBHs for several tens of orbits (∼ 40–60) in large regions of the parameter space [5-11]: i) at large","PeriodicalId":13304,"journal":{"name":"Il Nuovo Cimento D","volume":"108 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89008210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Chapman-Enskog method has been used to determine a first-order approximate solution to the BGK equations, which includes the transport features of shear viscosity, diffusion and thermal conductivity. Such approach leads to the constitutive equations and permits to close the reactive field equations at the Navier-Stokes, Fourier and Fick level. The propagation of plane harmonic waves in a reactive mixture where the transport effects are relevant can then be studied by a normal mode analysis. Numerical results are provided for two different mixtures of the hydrogen-chlorine system where the elementary reaction H2 +Cl ��HCl + H takes place. The behavior of diffusion, shear viscosity and thermal conductivity coefficients, as well as the one of phase velocity and attenuation coefficient, is described focusing the influence of the chemical reaction on the transport properties and harmonic wave solutions.","PeriodicalId":13304,"journal":{"name":"Il Nuovo Cimento D","volume":"79 1","pages":"103-110"},"PeriodicalIF":0.0,"publicationDate":"2010-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78098733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out in the large rotating tank of the Coriolis-LEGI laboratory in Grenoble. An ABL was created at reduced scale and measured. The mean flow was generated, both increasing (spin-up) and decreasing (spin-down) the rotation speed of the platform. Preliminary measurements by acoustic probes were used to assess the decay with time of the flow velocity at the position where turbulence measurements were subsequently performed. The mean velocity and the turbulence fields were then measured by using PIV (Particle Image Velocimetry) technique, which allows to obtain high-resolution measurements in the simulated ABL. For each rotation period and velocity conditions, two vertical cross-sections of the flow were measured at different times, then 3D velocity fields were reconstructed from the two planar fields under convenient geometric (orthogonal) and physical assumptions (reproducibility of the flow). The aim of this work is to collect a useful data set for testing and comparing turbulence models and parameterisations. For this reason, particular attention was paid to the turbulence statistics, turbulent fluxes and scales. The results of the data analysis are presented and discussed.","PeriodicalId":13304,"journal":{"name":"Il Nuovo Cimento D","volume":"8 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82558190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
