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
Particle shape effect on the viscosity and thermal conductivity of ZnO nanofluids
TL;DR: In this article, the authors investigated the viscosity and thermal conductivity of ZnO nanofluids with nanoparticle shapes of nearly rectangular and of sphere, under various volume concentrations of the nanoparticles, ranging from 0.05 to 5.0 vol.
Journal ArticleDOI
Heat transfer and pressure drop characteristics of nanofluids in a plate heat exchanger.
Yong Hoon Kwon,Doo-Gun Kim,Chengguo Li,Jung-Kun Lee,D S Hong,Jung-Goo Lee,Soowon Lee,Young-Ho Cho,Soo Hyung Kim +8 more
TL;DR: The experimental results pertaining to nanofluid efficiency seemed inauspicious and the overall heat transfer coefficient for 6 vol% Al2O3 increased to 30% because at the given viscosity and density of the nan ofluids, they did not have the same flow rates.
Journal ArticleDOI
On-road gaseous and particulate emissions from GDI vehicles with and without gasoline particulate filters (GPFs) using portable emissions measurement systems (PEMS)
Cavan McCaffery,Hanwei Zhu,Chengguo Li,Thomas D. Durbin,Kent C. Johnson,Heejung Jung,Rasto Brezny,Michael R. Geller,Georgios Karavalakis,Georgios Karavalakis +9 more
TL;DR: The results showed strong reductions in particulate mass (PM), soot mass, and particle number emissions with the use of GPFs, and nitrogen oxide (NOx) emissions showed improvements with the catalyzed GPFs in the underfloor position with the additional catalytic volume.
Journal ArticleDOI
Real-world NOx emissions from heavy-duty diesel, natural gas, and diesel hybrid electric vehicles of different vocations on California roadways.
Cavan McCaffery,Hanwei Zhu,Tianbo Tang,Tianbo Tang,Chengguo Li,Georgios Karavalakis,Georgios Karavalakis,Sam Cao,Adewale Oshinuga,Andrew Burnette,Kent C. Johnson,Kent C. Johnson,Thomas D. Durbin,Thomas D. Durbin +13 more
TL;DR: In this article, the authors assessed real-world nitrogen oxide (NOx) emissions from 50 heavy-duty vehicles of different vocations and engine technologies using portable emissions measurement systems (PEMS).
