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。Through the effort that the reform opens more than 20 years, many tour cities of china contain substantial development, but because of being limit by the various factors, the tour image of the city is not fresh and clear, also being tend in in travel the item development similar, this turn the faintness that the ineluctability causes the city travel the image, thus losing the competition ability. how set out from the oneself characteristics, mold the fresh and clear city tour image, become the chinese city tour development to need the problem for resolve in the day. the strand of harbin is a tour destination that has to develop the potential, the ice snow stanza contain international popularity, the festival and meetings travel certain advantage of the market occupancy, can integrate with whole packing of other winters tour item to carry on the market publicity
經過改革開放20多年的努力，中國許多旅遊城市有了長足的發展，但由於受旅遊資源特點、區位條件、旅遊配套設施等多方面因素的限制，城市的旅遊形象並不鮮明，在旅遊項目開發上也趨于雷同，這將不可避免的導致城市旅遊形象的模糊化，從而喪失競爭力。如何從自身特點出發，塑造鮮明的城市旅遊形象，成為中國城市旅遊發展中亟待解決的問題。哈爾濱是一個具有發展潛力的旅遊目的地，冰雪節有國際性的知名度，節慶和會議旅遊市場佔有一定的優勢，可以與其他冬季旅遊項目整體包裝整合進行市場宣傳。The un is also working to strengthen the global norm against weapons of mass destruction, end the sale of small arms to non - state groups, eliminate landmines, improve the protection of nuclear and chemical facilities, and increase vigilance against cyberterrorist threats
聯合國目前還在努力加強涉及以下方面的全球準則:反對大規模毀滅性武器、反對最後將小武器出售給非國家性集團、清除地雷、改進對核設施和化學設施保護以及增強對網路恐怖主義威脅的警戒。
