文摘
- •
Pool boiling heat transfer of gradient metal foams was investigated experimentally.
- •
The main influencing factors are layer number and foam material gradient.
- •
Departure bubble becomes smaller when it is colliding with the nickel foam skeleton.
- •
Surfactant effect is dependent on concentrations and nanoparticle deposition condition.
