Steady Two-Dimensional Non-Newtonian Flow Past an Array of Long Circular Cylinders up to Reynolds number 500: A Numerical Study

Abstract: Les modèles de cellules à surface libre et vorticité nulle ont été combinés aux équations de mouvement afi n d'étudier numériquement l'écoulement stationnaire de fl uides (rhéofl uidifi ants et rhéoépaississants) de loi de puissance incompressibles dans des groupes de longs cylindres. Les équations de mouvement exprimées sous forme de fonction de courant/vorticité ont été résolues numériquement à l'aide d'une méthode de différences fi nies précise au second ordre pour obtenir des données complètes sur le compo… Show more

“…Since a detailed discussion on the solution of the accuracy of the flow equations for the flow past an array of long cylinders is available elsewhere (e.g. see Soares et al, 2005b), the reliability and accuracy of the solution procedure for the thermal energy equation is presented here by comparing the present results with the literature values using the free surface cell model.…”

“…Preliminary comparisons between these predictions and the scant experimental results on heat transfer for both Newtonian and power law fluids have also been found to be encouraging (Mandhani et al, 2002;Mangadoddy et al, 2004) thereby lending credibility to the applicability of this approach. Likewise, it is also relevant here to mention that there have been only a few studies, even for the flow of and heat transfer from a single cylinder to power law fluids (Soares et al, 2005b;Bharti et al, 2006Bharti et al, , 2007. While all the aforementioned heat transfer studies have neglected the role of viscous dissipation, such procedure is not always justifiable (Winter, 1977;Carreau et al, 1997).…”
