摘要
测试了水在9根第2代机械加工表面多孔管(JK-2管)、1根第1代机械加工表面多孔管(JK-1管)和1根光滑管上的单管饱和池核沸腾传热系数,结果表明,JK-2管比JK-1管能更有效地强化水的池核沸腾传热.提出了一个新的池核沸腾强化传热机理,并导出了相应的池核沸腾强化传热关联式,该关联式与实验数据吻合良好.
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.
