文摘
- •
Spiral coil tube and paraffin/expanded graphite composite PCM were applied.
- •
Simulation of latent thermal energy storage unit was performed and validated.
- •
Heat transfer temperature difference has a higher impact than Reynolds number.
- •
Optimal radius ratio of spiral coil tube and PCM tank is determined.
- •
Increasing bulk density of PCM makes a faster thermal energy storage process.
