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。Then the coupling beams with new reinforcement layout were made an inquiry into, and the improvement on the seismic behavior by coupling beams diagonally reinforced with a few rows in end regions was found out at last, based on the observations of the experimental phenomena and the analysis of the measurement result, and by the comparison of seismic behavior by making use of hysteretic response, ductility and energy dissipation behavior, a conclusion is presented : the code for design and construction of reinforced concrete high - rise structures ( the draft asked for advise hi 2000 ) ca n ' t ensure that the coupling beams have fairly good seismic ductility ; the result of improvement of the seismic ductility of the coupling beams by the increase hi stirrups besides the strengthen of longitudinal detailing reinforcement was n ' t obvious ; the coupling beams diagonally reinforced with a few rows in end regions have fairly good mechanisms, and the ductility and the behavior of energy dissipation are better than conventionally reinforced concrete coupling beams, so it is suitable to te tised in short coupling beams
本文通過對三根小跨高比（均為l h = 1 . 0 ）剪力墻洞口連系梁在低周反復荷載作用下的試驗，了解了嚴格按《鋼筋混凝土高層建築結構設計與施工規程》 （ 2000年徵求意見稿）設計的連梁具有的抗震性能，研究了採取增大連梁配箍量同時加強縱向構造筋的方案對抗震性能的影響，並進一步對新的配筋形式的連梁進行了探討，了解了在連梁梁端配置多排交叉斜筋方案對連梁抗震性能的改善。通過對試驗現象的觀察和量測結果的分析，利用荷載?位移滯回曲線、延性和耗能性能等指標對各個試件的抗震性能進行了比較，最後得出結論： 《鋼筋混凝土高層建築結構設計與施工規程》 （ 2000年徵求意見稿）不能保證小跨高比連梁具有較好的抗震延性：通過增大連梁配箍量同時加強縱向構造筋的方案對改善連梁的抗震延性的效果不太明顯；梁端配置多排交叉斜筋的連梁具有相對較好的受力性能，其延性和耗能性能等各項性能指標均優于普通配筋連梁，宜在深連梁中採用。
