Abstract
To analyze the irreversibility and transportation of hybrid nano-powder inside a porous enclosure, CFD approach was utilized. Homogeneous model for predicting hybrid nanofluid features was utilized and non-Darcy model was used for implement of porous zone. To add the effect of MHD, new terms were added in flow equations. Irreversibility should be calculated if designer needs to know the maximum available work. Gravity force impact was considered which acts against the MHD. Outputs were summarized as contours and plots to depict the influences of Ha, permeability and Ra. To enhance the convective transportation, the gravity force and permeability should be increased. Besides, implement of MHD makes boundary layer to become thicker and velocity of operating fluid reduces. Rise of Da makes velocity to increase about 57.1% while it declines about 45.4% with grow of B. Augment of Ha results in smaller Nu about 6.97% while Be increases about 0.17%. With applying higher buoyancy force, Be decreases about 49.77 while the Nu for Ra = 1e5 is 4.21 time bigger than case of log(Ra) = 3. As Da increases, the value of Be decline about five percent but Nu intensifies by 16.45%.
