摘要
本研究旨在研究在池水沸腾情况下铜表面上的 CNT、GO 和 CNT + GO 纳米粒子涂层的比较分析。铜表面涂层采用浸涂法。在常压下对所有涂层表面进行池沸实验。水被用作工作流体。根据涂层表面特征和样品的池沸腾行为进行了比较。结果表明，铜表面的 CNT + GO 涂层在临界热通量（CHF）和沸腾传热系数（BHTC）方面更胜一筹。与裸铜表面相比，CNT + GO 涂层表面的临界热通量（CHF）和沸腾传热系数（BHTC）分别高出 129.19% 和 194.75%。还对所有样品进行了气泡动力学研究。
Experimental comparison of pool boiling characteristics between CNT, GO, and CNT + GO-coated copper substrate
The present investigation aims to study the comparative analysis of CNT, GO, and CNT + GO nanoparticle coatings on copper surfaces under a pool boiling situation. Coating on copper surfaces is performed using the dip coating method. Pool boiling experiments are conducted for all the coated surfaces at atmospheric pressure. Water is used as a working fluid. A comparison was made based on the coated surface characteristics and pool boiling behavior of the samples. The results show that CNT + GO coating on copper surfaces is better in terms of critical heat flux (CHF) and boiling heat transfer coefficient (BHTC). It is also observed that CHF and BHTC of the CNT + GO-coated surface are 129.19% and 194.75% higher, respectively, compared to the bare copper surface. Bubble dynamics studies were also performed for all the samples.
