Abstract : the distribution of cooling air which is in the grille - brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove. the influence of differential horizontal plates on the distribution of cooling air is discussed. the results show that original big circle round field of flow in the pillar - cavity is changed into full one - way field of flow and edges gas flow, at the same time, is increased by horizontal plates. there is a different function with horizontal plates and vertical plates. to make the uniform distribution of cooling air in the hot air stove, it is necessary that horizontal plates and vertical plates are used in a combined way
文摘:應用紊流三維數學模型模擬內燃式熱風爐內冷風在格子磚柱中的分佈，尋求改善其分佈的途徑.討論了加設不同布置的水平導流板對氣流分佈的影響.模擬結果表明，在支柱空腔內加設水平導流板改變了原有大迴旋流場，使迴旋流變成大面積的單向流.通過在支柱空腔內加設水平導流板可以發展邊緣氣流，這恰好與加設豎直導流板的作用相反，水平導流板和豎直導流板的結合使用有望實現冷風在格子磚柱中的均勻分佈Abstract : based on thestatic wind force factors of a tower and on the root - mean - square of the buffetingdisplacement responses of the tower top, which are measured by wind tunnel tests inlaminar and turbulent field respectively, the static and buffeting internal forces of thetower bottom control sections under its design wind speed are obtained by linearsuperposition method and fem
文摘:基於均勻流和紊流風場中的橋塔模型風洞試驗所測得的橋塔空氣力靜力系數及塔頂抖振響應的位移均方根，採用線性疊加法及有限元法反演，給出設計風速下塔底控制截面的順風向靜風及抖振內力。The flow of every pump is inclined to be different in the same side - inlet sump and the poor flow pattern, and then the inlet condition of the pump is not good, which makes the efficiency of the pump drop and causes vibration etc. based on the theses on the hydraulic characteristic of the wenshui road pumping station in the third period shanghai disposal sewage project, the methods were discussed to improve the flow pattern of side - inlet sump, and the measures were put forward to ameliorate the flow pattern in the paper
對側向進水集水池，一般會出現同池各水泵配水不均勻，池內流態紊亂、水泵吸水條件差，繼而導致水泵效率下降、機組振動等問題。本文結合上海市污水治理三期工程汶水路泵站水力特性研究課題，探討了改善側向進水集水池水力特性的途徑與方法，提出了有效的整流、均流措施。The extent of attenuation is proportional to the parameter under some assumptions in open channel flow. the lack of a sound theoretical basis for predicting the behavior of coarse particles means that experiments play a critical role
在明渠二維恆定均勻流條件下，經過適當簡化和假定得到的結果表明，懸移質運動起到減弱流體紊動強度的作用，制紊作用隨參數的加大而增強。The contents and original points of view are as follows : 1. the complete depth - averaged tubulence model is adopted to compare with the tradional depth - averaged model. the non - uniformity of velocity in z axis is considered in the former. the rigid - lid assumption, which was adopted for long time, is discarded, while the transpot equation of kinetic energy of dispersion is introduced. the 2d term ' s distribution of space - time is calculated
論文包含的主要內容及創新點有： 1 、引進了完全深度平均紊流模型，與傳統深度平均紊流模型相比，該模型計入了流速在深度方向分佈不均勻的影響；去掉了深度平均紊流計算中長期採用的「剛蓋假定」 ，同時模型通過引進離散動能的輸運方程，計算了二維離散項的時空分佈。Bf bag filter works by the principle of microfiltration. the liquid is purified in bags by passing small permeable pores. bagfilters can be used for large amounts of water
這樣液體可均勻分佈在整個濾袋的過濾表面，令整個層面中的流體分佈恆定一致，沒有紊流的負面影響，過濾效果好。分享友人
