cooled condition 中文意思是什麼
cooled condition
解釋
冷卻狀態-
The water temperature at the reactor pressure vessel outlet is about 330 degree c whereas the water temperature at the inlet of the vessel is about 290 degree c. the cooling water is in a sub - cooled condition at such high temperature and pressure to prevent it from boiling
反應堆出水的溫度約為攝氏330度，而入水口的溫度約攝氏290度。在這高溫及高壓狀態下的冷卻水會處于欠熱狀態即冷卻水的溫度與其沸點有一段距離，因此不會沸騰。 -
Compared with other general cfd software, the numerical modeling software of combustion process improved by the author of this paper has following features : ( 1 ) it can adjust the corresponding parameters and manipulating methods according to furnace architecture, operational parameters and fuels etc. ; ( 2 ) it can arrange the nodes of grid flexibly and also make special calculation to certain nodes, which cannot be accomplished by the general commercial software ; ( 3 ) in the boundary ( water - cooled wall ) condition processing, the third boundary condition is selected for the temperature calculating, linking the combustion process inside the furnace with the flow and heat exchange of water inside the water - cooled wall, so the heat absorbing and the influence of the water - cooled wall to combustion process and heat transfer of furnace are explicitly explained
與其它通用的cfd軟體相比，經論文作者所改進的燃燒過程數值模擬軟體的特點在於： （ 1 ）能夠結合爐子結構、運行參數及燃料等，調整模型中相應的參數及處理方法； （ 2 ）可以靈活的安排網格節點，對某些節點進行特殊處理； （ 3 ）在邊界（水冷壁）條件的處理上，溫度選用了第三類邊界條件，把爐內燃燒過程和水冷壁內工質的流動和換熱聯系了起來，使得水冷壁內的吸熱情況對爐內的燃燒和結渣的影響充分體現出來。
