This paper represents the heat transfer mechanism of a double-hulltanker under static and sloshing conditions. The objective is toinvestigate the heat transfer mechanism and the effect of forcedconvection induced by sloshing on cargo oil heating process. In theexperimental study, a large oil tanker side cabin is selected as theprototype, and the physical model is established on the basis of similarcriteria. Then the heat transfer mechanism is analyzed and the effect offorced convection on heat transfer under the sloshing condition isexplored through the analysis of the temperature curve and thederivation of the temperature. The experimental results show that, theoil temperature has obvious regional difference, the oil temperature inthe upper part of the coil is obviously increased, but the oil temperaturein the lower part of the coil has not changed obviously under the twoenvironments. At the initial phase of heating, although the temperatureof the monitoring point has not been significantly increased, there hasbeen a natural convection. In the middle stage of heating, naturalconvection is most intense, especially in the upper part of the coil understatic environment. The forced convection caused by sloshing reducesthe regional difference of the oil temperature on the upper part of thecoil and makes the heat transfer more balanced. The results suggest thata strictly theoretical optimization of the heating schemes in sloshingtanks can be used in future studies.
