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
Round-robin test on thermal conductivity measurement of ZnO nanofluids and comparison of experimental results with theoretical bounds
Wook-Hyun Lee,Chang-Kyu Rhee,Junemo Koo,Jae-Keun Lee,Seok Pil Jang,Stephen U. S. Choi,Ki-Woong Lee,Hwa-Young Bae,Gyoung-Ja Lee,Chang-Kyu Kim,Sungwook Hong,Younghwan Kwon,Doohyun Kim,Soo Hyung Kim,Kyo Sik Hwang,Hyun Jin Kim,Hyo Jun Ha,Seung-Hyun Lee,Chul Jin Choi,Ji-Hwan Lee +19 more
TL;DR: This study convincingly demonstrates that the large enhancements in the thermal conductivities of EG-based ZnO nanofluids tested are beyond the lower and upper bounds calculated using the models of the Maxwell and Nan et al. with and without the interfacial thermal resistance.
Journal ArticleDOI
Thermodynamic properties of five-layered HgBa2Ca4Cu5O12+y from equilibrium magnetization
Younghwan Kwon,Min-Seok Park,Jin-Hun Kim,K. Y. Choi,Myung-Hwa Jung,Akira Iyo,Kazuyasu Tokiwa,Young-Cheol Kim,Sung-Ik Lee +8 more
TL;DR: By using the Hao-Clem model, this article analyzed the equilibrium magnetization of the grain-aligned HgBa 2 Ca 4 Cu 5 O 12+ y (Hg1245) with T c ≃ 108 K.
