Can conductive elements optimize phase change processes in thermal energy storage systems?

This synergistic interaction between conduction and convection in the 20 mm rod case demonstrates how well-designed conductive elements can optimize phase change processes, achieving both rapid and uniform melting in thermal energy storage systems. Complete melting front advancement with optimal 20 mm rod configuration.

How effective are copper rods for thermal enhancement?

Among various thermal enhancement strategies, copper rods have proven particularly effective due to their high thermal conductivity (401 W/mK), which facilitates efficient heat transfer pathways within PCM storage systems 7.

Do copper rods improve heat transfer and mitigating melting time?

Total melting time and liquid fraction are associated as the performance metrics to be assessed at specific intervals to count the effect of rod integration. A comparative analysis is achieved against a no-rod baseline to evaluate the efficacy of the copper rods in improving heat transfer and mitigating melting time.

Is a 20 mm rod suitable for heat transfer enhancement?

These thermal patterns suggest that a 20 mm rod approaches the practical limit for heat transfer enhancement within this specific geometric configuration. The velocity field in Fig. 16 exhibits well-organized convection patterns that complement the rod’s conductive performance.

What is the thermal contact between copper rods and PCM?

The model also assumed ideal thermal contact between the copper rods used and PCM because the thermal conductivity of copper is high (401 W/m K) and the interfacial resistance was non-existent in comparable PCM-conductive enhancer systems when operated at steady-state conditions.

How conductive enhancement can improve thermal management in phase change systems?

Strategic conductive enhancement through copper rods offers a more effective and reliable approach to thermal management in phase change systems. Progressive melting time reduction with increasing rod length. Thermal gradient improvement across different rod configurations.
