Raúl E. Reupo Vallejos, Obidio Rubio ., Alexis Rodriguez ., Luis J. Caucha .


En este artículo, Formulamos un proceso fisiológico, a través de un problema de interacción fluido-estructura bidimensional entre el flujo de aire y el alvéolo pulmonar, en el marco de referencia Euleriano - Lagrangiano
Arbitrario (ALE). Este problema se origina al acoplar las ecuaciones del fluido y de la estructura, descritas por las Ecuaciones de evolución de Navier-Stokes para flujos incompresibles, y una ecuación de equilibrio,

Palabras clave

Interacción Fluido-Estructura; flujo de aire; alvéolo pulmonar; marco de referencia Lagrangiano- Euleriano Arbitrario (ALE); Ecuaciones de Navier-Stokes; Ecuación de Equilibrio
