Summary

The cargo hold ventilation arrangement of large container ships is essential for the safe transportation of refrigerated containers. This paper presents the mock-up experiments conducted to measure the volumetric flow rate and axial fan static pressure within a typical cargo hold’s spiral duct adjustable grille. Subsequently, a parametric model of the typical cargo hold was constructed using CATIA, and its ventilation arrangement was simulated with CFD. The parametric model facilitates the rapid construction of a CFD model for the cargo hold. The CFD simulation provides the average temperature and velocity distribution within the typical cargo hold, the volume flow rate of the adjustable air grille, the maximum fluid temperature of the refrigerated container, and the pressure drop across both the axial fan and the porous plate. The results indicated that the maximum fluid temperatures on the surface of the reefer containers were observed at the condenser exhaust fan outlets, all of which remained below the alarm threshold of 54 ◦ was approximately 45 ◦ C. Additionally, the average temperature within the cargo hold C. The volume flow rate at the outlets of the adjustable air grilles is approximately 4500 m³/h. The flow rate of the adjustable grilles from the top to the bottom of the cargo hold is relatively low in the third and fourth platforms, with the maximum flow rate occurring in the inner bottom.
