Abstract
الحمل الحراري المغناطيسي في فجوه متوازيه الاضلاع مفتوحه
Abstract
The present work examined numerically for the first time, the magneto-hydrodynamics
(MHD) natural convection flow and heat transfer in a fully opened parallelogrammic
enclosure filled with copper –water nanofluid and subjected to a straight magnetic
field. Both the upper and lower inclined walls of the enclosure are kept cold, while its
right sidewall is considered fully opened to the environment. The left sidewall of the
enclosure is heated partially, while the remaining parts of it are considered thermally
insulated. The ranges of this study are, Hartmann number (0 Ha 75), nondimensional
heat source location (0.25 0.75), Rayleigh number (104 Ra 106),
solid volume fraction (=0.04), and the inclination angle of the upper and the lower
walls (-60° 60°). The non-dimensional heat source length is considered fixed at [
= 0.25]. For all Hartmann numbers, It was found that for [Ra =106] , the maximum
value of the average Nusselt number corresponds to [-30° ≤ ≤ 0°] , [ = 0°] and [0°
≤ ≤ 30°] when the heat source location equals to [ = 0.25] , [ = 0.5] and [ = 0.75]
respectively.
