Research ArticleOpen accessIn the abstractNumerical Study of the Temperature Separation in the Ranque-Hilsch Vortex TubeSaeid Akhesmeh, Nader Pourmahmoud, Hasan SedgiThis research has been carried out in order to provide an understanding of the physical behaviors of the flow variation of pressure and temperature in a vortex tube. A computational fluid dynamics model is used to predict the flow fields and the associated temperature separation within a Ranque-Hilsch vortex tube. The CFD model is a steady axisymmetric model (with swirl) … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,316 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTime-Marching Method for Computations of High-Speed Compressible Flow on Structured and Unstructured GridK.C. Ng, M.Z. Yusoff, K. Munisamy et al.The development of Computational Fluid Dynamics (CFD) compressible codes for 2D structured quadrilateral grid and 3D unstructured hexahedral grid is described. The high-speed flow in a nozzle blade cascade is predicted numerically by solving the 2D/3D Euler Equations in a coupled manner. The new finite volume CFD solvers employ second-order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,348 accessesView PDF Cite
