Abstract	:	This study investigated the transient convection heat transfer in a rectangular packed duct with asymmetric heating The study involved both experimental and theoretical works. The experiments have been conducted in a rectangular packed duct with aspect ratio W/H of 4. Two different types of packing material have been used in the experiments, three sizes of expanded polystyrene spheres and two sizes of polyvinyl chloride Rashig Ring. The experimental runs for the different packing were conducted with heat flux in the range 20 to usd\rm 243\ W/m\sp2usd and Reynolds number in the range of 300 to 1550. The theoretical analysis of the problem was based on solving the one phase pseudo-homogeneous mathematical model. The study also investigated the significance of axial dispersion on the transient heat transfer process in a packed rectangular duct with heated top wall by a uniform heat flux and insulated bottom wall.
