Heat and Fluid Flow Characteristics of Nanofluid in A Channel Baffled Opposite to The Heated Wall

In this paper, a nanofluid-based solar collector duct equipped with baffles is examined numerically. Baffles are located on the back plate to guide nanofluid flow toward absorber for heat transfer enhancement purposes. Cu-water fixed rate and concentration in baffled investigated thermohydraulic mechanisms. different inclination angles, heights pitches considered study. Numerical simulations performed using Ansys fluent software verified results compared those of an experiment literature. The show that baffle angle 60° causes lowest performance. Because range 30 less variable while pressure loss increases sharply. At pitch 40 mm, there no reattachment point at non-heated surface. 90°, three eddies formed around baffle. slope linear regression analysis yields height has strongest effects performance followed by angle.
