Este estudio presenta una investigación numérica de la convección libre laminar entre placas verticales paralelas con temperaturas de pared uniformes y asimétricas. La pared derecha se mantiene a una temperatura más alta que la izquierda. El fluido entra al canal a una temperatura menor o igual a la de la pared más fría. Utilizando el método de volúmenes finitos en OpenFOAM v13, se resuelven las ecuaciones que rigen el proceso y se validan frente a soluciones analíticas clásicas. Un estudio sistemático de convergencia de mallas garantiza la independencia espacial. Los resultados muestran que, si bien el perfil de temperatura lineal se captura con precisión en mallas gruesas, el perfil de velocidad cúbico requiere una mayor resolución para mayor precisión. Los hallazgos validan la metodología numérica y ofrecen información crucial sobre los requisitos de la malla para simular con precisión flujos de convección natural completamente desarrollados en canales verticales.
