Research ArticleOpen accessIn the abstractAnalysis of the Application of Turbulence Models in the Calculation of Supersonic Gas JetIlina Ekaterina Evgenevna, Ilina Tamara Evgenevna, Bulat Pavel ViktorovichThis article considers the adequacy of the usage of various two-parameter differential turbulence models for the calculation of supersonic non-calculative (overexpanded and underexpanded) gas jet flowing into the environment that have a pressure equal to atmospheric. A brief historical background on the development of methods for calculating turbulent supersonic jet, which contain developed shock wave structures, is given. For each … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 7,199 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamics of Coherent Structures in the Coupled Complex Ginzburg-Landau EquationsTat-Leung YeeProblem statement: In this study, we study the analytical construction of some exact solutions of a system of coupled physical differential equations, namely, the Complex Ginzburg-Landau Equations (CGLEs). CGLEs are intensively studied models of pattern formation in nonlinear dissipative media, with applications to biology, hydrodynamics, nonlinear optics, plasma physics, reaction-diffusion systems and many other fields. Approach: A system of two … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 6 Nov 2012 · 6,990 accessesView PDF Cite
