In the present paper, the combined convection flow of an Ostwald-de Waele type power-law non-Newtonian fluid past a vertical slotted surface has been investigated numerically. The boundary condition of uniform surface heat flux is considered. The equations governing the flow and the heat transfer are reduced to local non-similarity form. The transformed boundary layer equations are solved numerically using implicit finite difference method. Solutions for the heat transfer rate obtained for the rigid surface compare well with those documented in the published literature. From the present analysis, it is observed that, an increase in leads to increase in skin friction as well as reduction in heat transfer at the surface. As the power-law index n increases, the friction factor as well as heat transfer increase.Dans cet article, on aétudié numériquement l'écoulement de convection combinée d'un fluide non-newtonien de loi de puissance de type Ostwald-de Waele en aval d'une surface perforée verticale. La condition limite d'un flux de chaleur de surface uniforme est considérée. Leś equations gouvernant l'écoulement et le transfert de chaleur sont réduitesà la forme de non-similarité locale. Leséquations de couche limite transformées sont résolues numériquement par la méthode des différences finies implicites. Les solutions pour la vitesse de transfert de chaleur obtenues pour la surface rigide se comparent bienà celles qui sont décrites dans la littérature scientifique publiée.À partir de la présente analyse, on observe qu'une augmentation de mèneà une augmentation du frottement superficiel ainsi qu'à une réduction du transfert de chaleurà la surface. Lorsque l'indice de loi de puissance n augmente, le facteur de friction et le transfert de chaleur augmententégalement.
