| Abstract Scope |
Iron and steel production emits massive high temperature flue gas, resulting in vast energy consumption and waste. Recovery and utilization of waste heat is better for improving energy efficiency, and energy-saving and emission reduction effect. Phase change materials (PCM) play an important role in energy storage, conversion, saving and utilization. In this paper, the Al-Cu-Si alloy PCM is selected for waste heat recovery. The effects of different number and geometric placement of heating tubes on temperature distribution and liquid-phase rate variation trade of Al-Cu-Si alloy during the melting and solidification process are further simulated and analyzed by ANSYS Fluent 2023 R1 software. The results reveal that the thermal conduction and natural convection are the two main heat transfer modes of Al-Cu-Si alloy melting. The heat exchange tubes located in the lower and middle part of the heat storage unit enjoy the faster melting time and solidification time, respectively. |
