A recent paper of Bardos & Titi [] has initiated the mathematical investigation of Onsager’s ‘ideal turbulence’ theory for wall-bounded flows, already followed by several works with improvements [2–4].These papers have all pursued the line of Onsager’s original mathematical analysis 1 from around 1945 [5–7], the …
La théorie d'Onsager a été élaborée en 1931 par Lars Onsager. C'est une théorie macroscopique du couplage linéaire de phénomènes irréversibles comme la conduction électrique et la diffusion thermique. Cette théorie émet l'hypothèse qu'il existe une relation linéaire entre les courants volumiques et les forces thermodynamiques.
