The blade inner channel cooling is a complex convection - conduction coupling problem. this thesis build a three - dimension. compressible turbulence model, and give a general solve method. with the geometrical model of the glossily rectangle straight channel, the rectangle straight channel with in - line arrays disturb plates, the rectangle straight channel with staggered arrays disturb plates, the rectangle straight channel with slant disturb plates, this thesis compute the flow and heat transfer condition when the cold air path though these channels, and gain the temperature field, pressure field, velocity filed, in addition. this thesis also analyze the influence of the different channel height, the different channel materials, the different channels, and gain the function relation between he nusselt number, friction factor and reynolds number. this thesis is emphasis on the new heat transfer enhancement structure, that is, disturb plates, with the comparison with the glossily channel and channel with pin fins, the heat transfer enhancement effect of the former is better, and the conclusion can be used in the design of aircraft blade
葉片內部通道冷卻是一個復雜的對流?導熱耦合傳熱問題，本文在分析葉片內部通道冷卻的流動與傳熱情況的基礎上，建立了三維、可壓縮紊流的物理模型，得到了通用的求解辦法；利用不帶擾流片的矩形直通道、帶順排擾流片矩形直通道、帶叉排擾流片、帶傾斜擾流片的矩形直通道的幾何模型，計算了冷卻空氣通過這幾種通道時的流動與換熱情況，得到了各種不同情況下計算區域的溫度場、壓力場、速度場；在此基礎上分析了不同的通道高度、不同的葉片通道材質對葉片內部通道冷卻的影響，並整理得到了各種通道形式下，努謝爾數和阻力因子與雷諾數的函數關系；本文重點研究了新型的葉片內部通道冷卻強化傳熱措施?帶擾流片的內部冷卻通道的強化傳熱效果，通過與光滑矩形直通道、帶針肋通道的冷卻效果的比較，表明了這種新型鮚構的優勢，對于葉片內部通道冷卻結構的設計可以起到指導的作用。Both ratio of average ( roa ) and cross - correlation method use local statistics to judge road. they perform good detection while smoothing speckle. moreover, they both have constant false alarm rate ( cfar ) which is important in radar target detecting
本文所採用的均值比例運算元和互相關運算元利用圖像局部的統計信息進行判決，在檢測道路基元的同時對圖像進行局部平滑以降低相干斑干擾;並且兩個運算元都具有恆虛警特性，門限值由給定的虛警概率確定。This paper tells an evaluation method based on statistical analysis of geology data ? according to the history of geology change and analysis of project geology about the research section of lidu slope of hurong national highway located in south - west of hubei province, based on abundant actual investigation and experimental data, stressing on tracing the history and rules of development of slope change, we divide the data of investigation and test into two classes, one is external physical feature and structural performance, the other is factor of internal and external dynamic environment, following the analysis of mathematics statistical analysis, which points out the proportion of foundation of geology judgement and puts forward a valid identification beacon of stability
本研究內容是一種以地質數據統計分析為基礎的評價方法。根據滬蓉國道南里渡滑坡研究區段的地質歷史演變結合工程地質類比法，以豐富的實際勘察、試驗資料為依據，以追索滑體的演化歷史和發展規律為重點，將滑體的勘察、試驗資料劃分為外部形態與結構性狀和內外動力環境因素兩大類，通過數理統計分析，給出地質判據的權重，提出切實可行的穩定性判別標志。從而對斜坡穩定性提出合理的、有說服力的綜合評價。Based on the major parameters deduced the traditional experiences and a lot of experiments, this paper brings forward a new, on hydrodynamics computing equation of the circulation oil volume of the lubrication system and the minimize pressure required in the main oil channel, also says briefly several part resistance coefficient which is used usually
以傳統的、由大量實驗而得出的發動機潤滑系統各主要參數為基礎，提出了一種新的、以流體力學為依據而得出的潤滑系統循環油量和各泄漏量的計算公式，以及主油道所需最低油壓的計算公式；簡要地介紹了潤滑系統中常見的幾種局部阻力系數。分享友人
