The thermal and flow characteristics at Ra = 107 were evaluated in a square cavity containing a circular cylinder in different places along the diagonal and horizontal centerlines. The enclosure contained non-Newtonian fluids of pseudoplastic and dil

Performance of second-moment differential stress and flux models for natural convection in an enclosure
Autor: Seok-Ki Choi, Ji-Woong Han, Hoon-Ki Choi
Publikováno v: International Communications in Heat and Mass Transfer. 99:54-61
In this paper the relative performance of two different differential stress and flux models for computing natural convection in an enclosure is examined. One model is the low-Reynolds number differential stress and flux model and the other model is a

Numerical study on heat transfer characteristics in branch tube type ground heat exchanger
Autor: Jae Hun Pak, Geun Jong Yoo, Changhee Lee, Hoon Ki Choi
Publikováno v: Renewable Energy. 115:585-599
A ground heat exchanger is an essential component of ground source heat pumps, which saves cooling and heating energy effectively. In this study, a branch tube type heat exchanger is suggested for a ground heat exchanger instead of commonly using the
