Journal of thermal analysis and calorimetry Vol. 144, № 4. P. 1389-1399Abstract: Mixed convection in vertical parallel channels is analyzed with the viscous fuid sandwiched between nanofuids within porous material flled in a vertical channel. The concept of single-phase transport of nanofuids is employed to defne the nanofuid fow and heat transfer and the Darcy approach is incorporated to describe the circulation within the porous material. Formulated ordinary diferential equations which are non-linear and coupled along with the corresponding boundary and interface conditions are solved by the regular perturbation method. The main objective is to investigate the efects of the Grashof and Brinkman numbers, solid volume fraction, porous parameter on the velocity and temperature felds. Results are shown in the graphical and tabular form. The physical characteristics governing the fow such as skin friction and rate of heat transfer are also investigated considering fve diferent materials of nanoparticles.
