영문 초록

It is a main object to find out the effect of curvature of pipe on the thermal flow field in copper pipe. The toroidal coordinate system is chosen for this project. 3-D numerical works are done by a commercial code, PHOENICS. The flow and temperature field are simulated and analysed on the view point of variation of pressure and temperature with Dean number. The results show that the strong recirculation phenomena and secondary flow are established and then a lot of pressure drop along main flow direction occurs at the curved portion of pipe and that the temperature variation has a reversed trend of pressure variation along the axis of pipe.
