Abstract
Copper foam-based composite phase change materials (CPCMs) show great potential for thermal management in aerospace applications. However, their performance can be significantly influenced by unsteady force fields. In this study, CPCMs were prepared using paraffin and copper foam (97 % porosity, 20 PPI), and ten variable force field conditions—varying in both direction and intensity—were tested. Results show that force fields mainly affect thermal control by altering convection during melting. As the melting area expands, the influence becomes more pronounced. A late-phase shift to a positive force field increases the risk of thermal runaway. In phase IV, temperature rises under 1 g, 3 g, and 5 g were 59.5 %, 103.9 %, and 149.8 % higher than under 0 g, respectively. In contrast, negative force fields induced cooling, with -5 g yielding the longest cooling duration and a maximum temperature drop of 6.19 °C. Notably, both increasing positive force field intensity and decreasing negative force field intensity caused brief temperature spikes, degrading thermal control performance. However, this adverse effect tended to level off when the positive force field intensity exceeded 3 g. The study also analyzed the impact on temperature distribution and CPCM utilization. These findings provide theoretical guidance for optimizing CPCM-based thermal management systems.
