the object studying in this article is too large . the dimension is 53mx 15.4nx 15.5m and the total mesh number is over one million which cannot be calculated by current personal computer 由于本電站廠房空間高大,尺寸為53m15.4m15.5m,粗略劃分網(wǎng)格數(shù)超過百萬,現(xiàn)有計算機資源很難滿足計算要求。
according the symmetry principle, minimize the model one third the size of the former model . the mesh number is greatly decreased which successfully solve the problem of lacking of computer resource 本文采用計算區(qū)域的簡化處理,根據(jù)射流對稱特點,將整個計算區(qū)域簡化為原來的13,計算網(wǎng)格數(shù)大大減少,計算時間亦大大縮短,有效地解決計算機資源不足的問題。
abstract : the effects of sodium hydroxide concentration and chlorination temperature on effective chlorine content of calcium hypochlorite were tested . the effects of mesh number of standard sieve on effective chlorine content of calcium hypochlorite were tested . the retrieval technology of effective chlorine in mother liquor of calcium hypochlorite was researched, and the effects of cycle number on effective chlorine content of calcium hypochlorite were tested . the results indicate that when sodium hydroxide concentration is 333.3 g / l, and chlorination temperature is 20, the effective chlorine content of calcium hypochlorite is highest, that when mesh number of standard sieve is 180 mesh, the effective chlorine content of calcium hypochlorite is higher, but the passing sieve rate is not too low, that the cycle number has no remarkable effect on the effective chlorine content of calcium hypochlorite, and the effective chlorine content of calcium hypochlorite is basically above 80 % 文摘:測試了燒堿質(zhì)量分數(shù)和氯化溫度對漂粉精有效氯含量的影響,測試了分鹽用標準篩目數(shù)對漂粉精有效氯含量和過篩率的影響.研究了漂粉精母液中有效氯的回用工藝流程,并測試了循環(huán)次數(shù)對漂粉精有效氯含量的影響.結果表明,燒堿質(zhì)量分數(shù)為25、氯化溫度為20時,漂粉精的有效氯含量最高;標準篩目數(shù)為180目時,漂粉精的有效氯含量較高而過篩率不太低;循環(huán)次數(shù)對漂粉精有效氯含量沒有顯著影響,并且漂粉精有效氯含量基本上可以達到80以上
