Thermodynamique Résumé : The classical problem of forced convection boundary layer flow and heat transfer past a needle with variable wall temperature using nanofluids is theoretically studied. The similarity equations are solved numerically for two types of metallic or nonmetallic, such as copper (Cu) and alumina (Al2O3) nanoparticles in the based fluid of water with the Prandtl number Pr=7 to investigate the effect of the solid volume fraction parameter phi of the fluid and heat transfer characteristics. The skin friction coefficient, Nusselt number, and the velocity and temperature profiles are presented and discussed. It is found that the solid volume fraction affects the fluid flow and heat transfer characteristics.

Fully developed mixed convection in a vertical channel filled by a nanofluid / T. Grosan in Journal of heat transfer, Vol. 134 N° 8 (special issue) (Août 2012)  

Public ISBD [article]  inJournal of heat transfer > Vol. 134 N° 8 (special issue) (Août 2012) . - 05 p. Titre : Fully developed mixed convection in a vertical channel filled by a nanofluid Type de document : texte imprimé Auteurs : T. Grosan, Auteur ; I. Pop, Auteur Année de publication : 2012 Article en page(s) : 05 p. Note générale : heat transfer Langues : Anglais (eng) Mots-clés : vertical channel  fully developed flow  nanofluid  Buongiorno model Index. décimale : 536 Chaleur. Thermodynamique Résumé : The steady fully developed mixed convection flow between two vertical parallel plates with asymmetrical thermal and nanoparticle concentration conditions at the walls filled by a nanofluid is studied. The nanofluid model used in this paper takes into account the Brownian diffusion and the thermophoresis effects, and the analysis is based on analytical solutions. Thus, analytical expressions for the fully developed velocity, temperature, and nanoparticle concentration profiles as well as for the Nusselt and Sherwood numbers at the left wall of the channel are given. A numerical solution has been also obtained and compared with the analytical solution, the agreement being very good.
