Stability analysis of a closed thermosyphon
European Journal of Applied Mathematics, 1990 This paper deals with the motion of a fluid in a closed loop under the effect of natural convection and a given external heat flux. More precisely, we show that the stationary solutions of a system describing the intermediate asymptotics of the previous problem are structurally linearly unstable.

Heat transfer and pressure drop in a reverse thermosyphon loop
, 2016 碩士逆流熱虹吸迴路發展的目的，是為了解決目前工業用熱虹吸式熱管礙於流體受熱膨脹向上流動，被迫只能配合傳統虹吸傳熱模式開發或外加機械泵迴路解決只能大量向上熱傳的瓶頸。透過蒸汽壓與重力的特殊設計，可達成自主向下循環並大量傳熱的目的，有著不須外部供電，簡單的結構和限制單方向熱流的特點。 本實驗工作流體為酒精，充填率60%，輸入功率由10W至50W，、傾斜角度及改變向下傳熱管長度1850mm、350mm。實驗在改變蒸發端容積後，於輸入功率46W、充填率60%、向下傳熱管長度350mm時，藉由觀察T6的溫度上升 ...

Numerical simulation of heat and mass transfer in a closed two – phase geothermal thermosyphon
MATEC Web of Conferences, 2017 Mathematical model of the heat and mass transfer process in a two-phase thermosyphon with allowance for the coolant phase transformations is presented in this study. The formulated boundary-value problem was solved by the finite differences method.
