PTFE Modification to Enhance Boiling Performance of Porous Surface

Ya-Qiao Wang, Jia-Li Luo, Yi Heng, Dong-Chuan Mo, Shu-Shen Lyu
Proc. ASME. MNHMT2019, ASME 2019 6th International Conference on Micro/Nanoscale Heat and Mass Transfer, V001T04A009, July 8–10, 2019
Paper No: MNHMT2019-4208
DOI: https://doi.org/10.1115/MNHMT2019-4208
... is always carried out on plain or flat surface. In this paper, we coated PTFE powders on superhydrophilic micro copper dendrite fin surface to build wetting hybrid surface. The pool boiling experimental results showed that after coating, the wall superheat dramatically decreased to 8 K, which is 9K lower...

Experiment of Enhanced Pool Boiling Heat Transfer on Coupling Effects of Nano-Structure and Synergistic Micro-Channel

Linsong Gao, Jizu Lv, Minli Bai, Chengzhi Hu, Liqun Du, Yubai Li
Proc. ASME. MNHMT2019, ASME 2019 6th International Conference on Micro/Nanoscale Heat and Mass Transfer, V001T04A010, July 8–10, 2019
Paper No: MNHMT2019-4215
DOI: https://doi.org/10.1115/MNHMT2019-4215
... Abstract The manipulation of micro- or nano-structure is a promising method to improve pool boiling heat transfer performance. However, most studies just focus on the micro- or nano-structure without considering the combination micro- and nano-structure. In this paper, we fabricated synergistic...

Pool Boiling Heat Transfer of Borated (H 3 BO 3 ) Water on a Nanoporous Surface

Miguel Amaya, Sang M. Kwark, Ajay Gurung, Seung M. You
Proc. ASME. MNHMT2012, ASME 2012 Third International Conference on Micro/Nanoscale Heat and Mass Transfer, 163-174, March 3–6, 2012
Paper No: MNHMT2012-75041
DOI: https://doi.org/10.1115/MNHMT2012-75041
... With regard to potential application in pressurized water reactors (PWRs), a nanoporous heated surface was tested in pool boiling of an aqueous solution of boric acid (H 3 BO 3 ), or borated water (1% volume concentration). The effect of different system pressures and different surface...
