Simulación numérica directa en turbulencia

Abstract

Este artículo describe la técnica numérica conocida como Simulación Numérica Directa (DNS) en Mecánica de Fluidos. Esta aproximación resuelve numéricamente las ecuaciones de Navier-Stokes sin ninguna simplificación tanto en flujos laminares como turbulentos (es decir, sin emplear modelos de turbulencia). Finalmente se presentan resultados en dos casos concretos: mezcla de dos escalares en turbulencia homogénea y estacionaria y combustión de una mezcla estratificada.

This paper describes the numerical technique known as Direct Numerical Simulation (DNS) applied to Fluid Mechanics. Under this approach the Navier-Stokes equations are numerically solved without additional hypothesis for both, laminar and turbulent flows (i.e., without any turbulence model). Finally, two specific cases are considered where results are presented: mixing of two scalars in homogeneous and steady turbulence and combustion of a stratified mixture.
