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53m 15 . 4m 15 . 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1 3 ,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(biāo)準(zhǔn)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(jié)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(biāo)準(zhǔn)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
