Sažetak
Abstract: Floating platforms using ice as a support structure are a promising candidate for replacing the conventional floating platforms due to their favorable characteristics, i.e. lower initial investment and manufacturing costs, reasonable operational costs, sufficient load capacity and strength. The new experimental setup was recently developed to enable conducting experiments during transient solidification/melting of water inside an insulated tank with purpose to give a more detailed insight of the temperature distribution inside the tank and the influence of the coolant inlet temperature on the formation of ice. This work expands the experimental research by developing a three- dimensional computational fluid dynamics (CFD) model for transient heat transfer during the solidification/melting of ice around the cooling pipes inside the experimental setup. Since the solidification/melting model cannot be used for compressible flows the analysis considers the latent heat of fusion and constant water properties. The analysis is carried out to determine the influence of the coolant inlet temperature on spatially resolved formation of ice in the experimental tank. The CFD model also accounts for the change in the coolant temperature during the passage through the tank and the heat transfer through the insulation plates. Additional CFD analysis was performed without solidification/melting model but with realistic water/ice properties (i.e. density and viscosity are temperature dependent). This analysis represents reference point for future improvements of the CFD and experimental model. Furthermore, the CFD results are compared with the experimentally obtained data and the results are used to determine the future steps for improving the concept and consequently up-scaling for commercial applications.
