LOPEZ-ZAMORA, L. y MUNOZ-COBO, J.L.. Turbulence Analysis with the k-e Model, Using a Three-Dimensional Code with High Order Schemes. Inf. tecnol. [online]. 2004, vol.15, n.2, pp. 25-28. ISSN 0718-0764. doi: 10.4067/S0718-07642004000200005.
A three dimensional code was developed using high order schemes and the k-e model to evaluate turbulent phenomena in a pipe with fully developed flow. The methodology establishes the solution of a set of differential equations with SOU-ULTIMATE and QUICKES-ULTIMATE schemes, to attain equilibrium between precision and applicability. Results obtained with the TURBUL model, were compared with three experimental data sets and then compared with 10 different methodologies that use the same k-e model but with some of the parameters adjusted. It is concluded that evaluations of turbulent kinetic energy, energy dissipation rate, and eddy viscosity using different Reynolds numbers were adequate, offering the advantages of shorter computational time
