© Avestia Publishing, 2017.A numerical study of conjugated heat transfer in ceiling-slot refrigerated containers is carried out to analyze the temperature distribution effectiveness. The refrigerated container is represented by a fixed cross-sectional area but its length sequentially varied as 6.13m, 8.33m, and 13.3m, and is under turbulent flow regime. Besides, the effect of slot size on thermal characteristics is studied by considering half-span injection. The container walls are defined as conductive opaque and are interacting with outside environment. The air velocity at the slot exit is varied depending upon the injection Reynolds number between 2×104 ≤ Re ≤ 2×105. The gravity effect is taken into account, and the coupled mass, momentum, and energy equations are discretized in finite volumes by implementing the Reynolds Stress Model to predict the turbulence stresses. The resulting heat transfer coefficients are presented as plots of the mean Nusselt number versus the modified Reynolds number.
