For many years, the drying furnace has been adopted with sealed structure and electrical heated, dial instruments are used to control the temperature of the drying furnace and to keep it invariable. parameter setting is inputted by manual method, heating time is completely controlled by operators ’ experiences or their moods, meanwhile, its control function is singular, not only having no automatic heating time and insulating monitoring, having no drying process monitoring, but also having no function of automatic recording and report printing, the workers ’ labor intensity is bigger. thus two abnormal situations are always come forth, one is the insulating performance and intensity of works cannot be guaranteed reliably, it perhaps need to be dried repeatedly, the other is always to extend the drying time in order to ensure the drying quality
多年來乾燥爐一直採用悶罐式結構和電加熱方式，溫度控制採用指針式溫度控制儀表來實現爐溫的恆定，其參數設定由人工輸入，時間控制則完全憑操作者的經驗、情緒來掌握，其控制功能單一，沒有時間控制、絕緣自動監測功能，也沒有乾燥過程監視功能，更沒有多要素記憶、列印存檔功能，工人的勞動強度較大，所以就經常出現兩種異常結果:一是工件的絕緣性能和強度得不到可靠保證，需要反復乾燥;另一種是為保證乾燥質量，往往要延長乾燥時間。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
