The use of molecular spectra simulation for diagnostics of reactive flows

The C 2 * radical is used as a system probe tool to the reactive flow diagnostic, and it was chosen due to its large occurrence in plasma and combustion in aeronautics and aerospace applications. The rotational temperatures of C 2 * species were determined by the comparison between experimental and theoretical data. The simulation code was developed by the authors, using C++ language and the object oriented paradigm, and it includes a set of new tools that increase the efficacy of the C 2 * probe to determine the rotational temperature of the system. A brute force approach for the determination of spectral parameters was adopted in this version of the computer code. The statistical parameter c 2 was used as an objective criterion to determine the better match of experimental and synthesized spectra. The results showed that the program works even with low-quality experimental data, typically collected from in situ airborne compact apparatus. The technique was applied to flames of a Bunsen burner, and the rotational temperature of ca. 2100 K was calculated.

Impacto das tecnologias de informação e comunicação: cultura digital e mudanças sócio-culturais

The contemporaneous culture presents new con ditions of interaction with the information flows in the knowledge construction. Multidimensional codifications stimulate the brain and impress meaning to concepts initially empty. Culture is redefined as mosaic-culture, composed by a diversity of media and by immersion in the messages' sphere. In emerge nt countries like Brazil that propose to capacitate citizens for action and for interaction, the aims should imply the respect to the cultural specificities and in the real improvement of the citizens welfare. Information Science in this context must seek theorizations and practices that contribute to social improvements, capacitating and a better understanding of the challenges of Social Web. If the PISA examination demonstrates the County's frailness relating to the information, the 2011 Unicef report point to opportunities. The Universities have an essential role in the capacitating and in the creation of professional contingents, developing their own potentialities in the study, research and knowledge production for a better use of the Information and Communication Technologies. The man-machinery interfaces offer new problems to be dealt together with the literacy lags in Brazil: if information needs to be communicated to re-elaborate in knowledge, its representational supports need to be learnt as technological processes. Implementing informational ambiences studies will produce material for analyses, for the understanding and for the cultural practices importation, converting them to the contextualization of the Country's needs.

Numerical assessment of mass conservation on a MAC-type method for viscoelastic free surface flows

A numerical study of mass conservation of MAC-type methods is presented, for viscoelastic free-surface flows. We use an implicit formulation which allows for greater time steps, and therefore time marching schemes for advecting the free surface marker particles have to be accurate in order to preserve the good mass conservation properties of this methodology. We then present an improvement by using a Runge-Kutta scheme coupled with a local linear extrapolation on the free surface. A thorough study of the viscoelastic impacting drop problem, for both Oldroyd-B and XPP fluid models, is presented, investigating the influence of timestep, grid spacing and other model parameters to the overall mass conservation of the method. Furthermore, an unsteady fountain flow is also simulated to illustrate the low mass conservation error obtained.

Three-dimensional transient complex free surface flows: Numerical simulation of XPP fluid

In this paper we present a finite difference MAC-type approach for solving three-dimensional viscoelastic incompressible free surface flows governed by the eXtended Pom-Pom (XPP) model, considering a wide range of parameters. The numerical formulation presented in this work is an extension to three-dimensions of our implicit technique [Journal of Non-Newtonian Fluid Mechanics 166 (2011) 165-179] for solving two-dimensional viscoelastic free surface flows. To enhance the stability of the numerical method, we employ a combination of the projection method with an implicit technique for treating the pressure on the free surfaces. The differential constitutive equation of the fluid is solved using a second-order Runge-Kutta scheme. The numerical technique is validated by performing a mesh refinement study on a pipe flow, and the numerical results presented include the simulation of two complex viscoelastic free surface flows: extrudate-swell problem and jet buckling phenomenon. © 2013 Elsevier B.V.
