Cet article présente l'étude d'un mur solaire de type Trombe composite intégrant une paroi stockeuse constituée d'un mortier ciment contenant un matériau à changement de phase micro-encapsulé. Un modèle numérique de ce mur solaire a été développé en utilisant le logiciel Dymola/Modelica. Les résultats issus de simulations sont comparés à des mesures expérimentales réalisées sur une maquette à échelle réduite en vue d'une validation du modèle. Les résultats numériques et mesurées obtenus montrent une bonne similitude pour les grandeurs caractéristiques du composant solaire essentiels à l'évaluation de ses performances énergétiques |
