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.
Single-tube saturated pool nuclei boiling on 9 2nd generation machined porous tubes (JK-2 tubes), 1 1st generation machined surface porous tube (JK-1 tubes), and 1 smooth tube was tested Heat transfer coefficient.The results show that JK-2 tube can enhance the nucleate boiling heat transfer of water more effectively than JK-1 tube.A new heat transfer mechanism of nucleate boiling heat transfer is proposed and the corresponding nucleate boiling Intensified heat transfer correlation, the correlation and experimental data agree well.
