Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
文摘:應用計算機模擬的方法,在不考慮燃燒的冷態情況下,研究了熱風爐燃燒室內的氣流分佈規律.在此基礎上,比較了2種不同設計方案的氣流流動特徵,尤其是研究了燃燒器空氣通道內阻流板的設置與否對空氣和煤氣的流動和混合的影響.結果表明,阻流板的設計對加強空氣和煤氣的混合有著極為重要的作用,同時也增加了空氣管道的阻力損失,在同樣的工況條件下需要提高管道系統的總壓力A two - dimensional double diffusive laminar natural convection in rectangular enclosure is detailed analyzed. the results show that when the thermal and solutal buoyancies aid each other, the airflow consists of one main cellular structure and is steady, regardless of the relative strength variation between the heat and pollutant sources. there are multiple flow structures, however, according to the relative strength when the buoyancies opposing each other
模擬結果表明雙擴散自然對流系統的空氣流動與傳熱傳質特性完全是由離散熱源與污染源浮升力之間的相互作用關系訣定的:當離散熱源與污染源浮升力協同作用時,自然對流呈比較穩定的單一流動結構;而當熱源與污染源浮升力對抗作用時,自然對流系統隨它們之間強度變化呈現出多種流動狀態。A new method is put forward on thermodynamics combustion model to make imitating research on egr - a software is made to calculate the amount of no from the gasoline by connecting with the practical condition in our country, starting with thermodynamics and experiment at the same time make a system research to influence by the exhaust gas returning system on the gasoline, such as exhaust gas, fuel economy, and power, finally a new thought is afforded for optimizing all the egr parameter in chapter 6
第五章採用上述診斷和預測模型對bj492q發動機進行了模擬計算和實驗研究,並探討了點火提前角、殘余廢氣系數、燃空比、壓縮比和火花塞位置對發動機性能的影響。第六章提出了基於熱力學燃燒模型對egr進行數值模擬的方法,系統地研究了車用汽油機加裝egr系統后對排放、油耗、功率的影響,並結合排放標準。提出了egr參數的全局優化的新思路。Phenomena, such as flow field confusion and slagging etc. have occurred in the practical process of cyclone burner for coal - water slurry ( cws ) firing, on this basis a study on aerodynamic field of cws cyclone burners had been carried out through cold state experiments in the laboratory, then the influence of burner ' s structure properties upon the said flow field had been carried out, and expected to find more reasonable structure of the burner was found. in my study the focus is on the affection of cone and cyclone intensity in the condition of infinite and finite fields
本文著重研究現有水煤漿旋流燃燒器的旋流葉片角度,一次風擴口的長度以及角度對旋流燃燒器出口流場的影響,通過流場的比較,以期得到性能較好的旋流燃燒器。考慮到水煤漿燃燒器中心的水煤漿射流對于其空氣動力場的影響,本文在實驗室冷態實驗研究的基礎上,模擬水煤漿射流,研究其對燃燒器空氣動力場的影響。In this paper, the author deduces the air dynamic and torque transmission system model for the 1. 3 mw active stall wind turbine, then founds the control model under the simulink circumstance. and does the output power simulation based on the certain wind speeds. then confirms the coefficients ki and kp
