Journal ArticleDOI
Convective heat transfer characteristics of nanofluids under laminar and turbulent flow conditions
Doohyun Kim,Younghwan Kwon,Yonghyeon Cho,Chengguo Li,Seongir Cheong,Yujin Hwang,Jaekeun Lee,Daeseung Hong,Seongyong Moon +8 more
TL;DR: In this article, the effect of nanofluids on convective heat transfer was investigated through a circular straight tube with a constant heat flux condition in the laminar and turbulent flow regime.
Journal ArticleDOI
Investigation on characteristics of thermal conductivity enhancement of nanofluids
Yujin Hwang,Young-Chull Ahn,Hyun-Suk Shin,Chan Gyu Lee,Gyoo-Cheon Kim,Hyean-Cheal Park,Jaekeun Lee +6 more
TL;DR: In this paper, the thermal conductivity enhancement of water-based MWCNT nanofluid is increased up to 11.3% at a volume fraction of 0.01.
Journal ArticleDOI
Thermal conductivity and lubrication characteristics of nanofluids
TL;DR: In this paper, various nanoparticles, such as multi-walled carbon nanotube (MWCNT), fullerene, copper oxide, silicon dioxide and silver, are used to produce nanofluids for enhancing thermal conductivity and lubrication.
Journal ArticleDOI
A study on the tribological characteristics of graphite nano lubricants
TL;DR: In this article, graphite nanoparticles were used to fabricate nano lubricants with enhanced tribological properties and lubrication characteristics, and the results showed that when comparing fixed plates coated with raw and nano-lubricants, the plate coated with a nano lubricant containing graphite nanarticles had a lower friction coefficient and less wear.
Journal ArticleDOI
Effect of the size and morphology of particles dispersed in nano-oil on friction performance between rotating discs †
Yujin Hwang,Chang-Gun Lee,Young Min Choi,Seongir Cheong,Doohyun Kim,Kwangho Lee,Jaekeun Lee,Soo Hyung Kim +7 more
TL;DR: In this paper, various carbon-based particles such as graphite, carbon black, graphite nanofibers and carbon nanotubes were dispersed in mineral oil to systematically examine the effect of the size and shape of particles on the properties of friction performance.
