The nucleate pool boiling heat transfer coefficients of water on 9 JK-2 tubes
a JK-1 tube and a smooth tube were measured. The results indicated that the JK-2 tubes can more effectively enhance the nucleate pool boiling heat transfer of water than the JK-1 tube. A new mechanism of enhanced nucleate pool boiling heat transfer was proposed
and a corresponding correlation of enhanced nucleate pool boiling heat transfer was developed. The correlation was in good agreement with the experimental data.
