Studying the heat - mass transfer and multi - spices electric - chemical reaction, a dynamic temperature model was deduced for molten - carbonate fuel cell stack. the thermal radiation, shift reaction, and the change of gas spices were considered in this model. establishing momentum equation, the paper has developed a 3d temperature and flow fields model for mcfc stack based on cfd technique
建立了熔融碳酸鹽燃料電池堆內部單體的暫態溫度模型,並考慮了電堆的輻射換熱、轉換反應、反應氣體組分變化對溫度場的影響;根據mcfc的微分控制方程組,考慮氣體組分的熱力學性質及動量變化的影響,利用數值分析方法求解熔融碳酸鹽燃料電池堆的三維流場與溫度場,分析了各作用因素對熔融碳酸鹽燃料電池堆溫度分佈的影響機制。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。The forming - nucleus drive power could form numerous little crystal nucleus under natural melting temperature. the formation of tic particles in the melt could be divided into two phases which was forming - nucleus and growth. the forming mechanism of tic was : melting ti first surrounded c, then ti melting in the alloy and c formed a complicated reaction mesosphere on the carbon surface
根據熱力學及動力學分析,認為在碳顆粒界面處tic的形核率很高,形核驅動力足以在正常的熔煉溫度下形成眾多的小晶核;熔體中tic顆粒的合成可分為形核與長大兩個階段,其形核機制為:首先活性ti原子包圍c ,溶入合金中的ti與c在碳表面形成一復雜反應中間層,隨著反應進行, ti和c顆粒不斷減少,生成的tic不斷彌散分佈於熔體中;其長大過程伴隨著tic顆粒的相互堆砌、聚集和形態規則化。
