Euler and Navier-Stokes Solvers Using Multi-Dimensional Upwind Schemes and Multigrid Acceleration
No full textImplementation and Validation of the Spalart-Allmaras Turbulence Model for Application in Hypersonic Flows
No full textThe Spalart and Almaras turbulence model has been implemented
in a finite volume code using a implicit finite difference technique.
A wide range of turbulent flows have been computed
in validation phase and numerical results are shown.
A special attention is paid to the hypersonic applications. A hypersonic
wind tunnel flow and a Mach 5 flow over a hollow-cylinder-flare have been
considered and a critical comparison between the numerical results and
experimental data is reported

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
