To analysis the heat environment in the turbine , it ' s required to couple a flow solver with a conduction heat transfer solver 本文從實驗和計算的角度對渦輪葉片中的流場、溫度場耦合進行了研究。
Based on unsymmetrical heat environment , boresight error , boresight error slope and transmission coefficient of a specific shape radome have been calculated with indirect ray method 在不對稱熱環(huán)境的基礎(chǔ)上,采用間接射線法計算天線罩瞄準誤差、瞄準誤差斜率及功率傳輸系數(shù)。
Through abundant surveys and experiments , we introduced the theory of fuzzy mathematics , and built a fuzzily comprehensive evaluation model for heat environment of air - conditioner in truck 通過大量的調(diào)查與實驗,引入模糊數(shù)學(xué)理論,建立了汽車空調(diào)熱環(huán)境的模糊綜合評價模型。
Importance must be attached to guarantee full vegetation of stadiums and three - dimensional designs of buildings , equipment , structures as well as acoustic , lighting , electrical and heating environments 重點推進場館的綠化、建筑、設(shè)備、結(jié)構(gòu)和聲光電熱環(huán)境的三維可視化設(shè)計。
Finally , it makes an assessment , taking when as an example , on the indoors heat environment and the analysis in terms of technology and economy of green buildings in the areas which are hot in summer and cold in winter 論文還以武漢為實例,評價了夏熱冬冷地區(qū)的室內(nèi)熱環(huán)境以及綠色建筑的技術(shù)經(jīng)濟分析,闡述了綠色建筑能更好地實現(xiàn)社會、經(jīng)濟、環(huán)境效益的統(tǒng)一。
The missile with its radome is at high temperature during the entrance . due to aerodynamics heating process , the high temperature cause air ionization and ablation of the radome , so the radome is at unsymmetrical heat environment , its electrical properties vary with different parts of the radome 導(dǎo)彈在再入過程中,由于空氣動力加熱效應(yīng),引起空氣電離和天線罩表面被燒蝕,因此,天線罩處于不對稱熱環(huán)境中,它各部分的介電性能不同。
Thirdly , this dissertation briefly introduces the engineering estimation method of the aerodynamic heat and supplies the simplified formulas . not considering the rejection , the ablation and some other factors , the author calculates the stagnation heat flux and the non - stagnation field heat flux distribution of some fly situation as the example aerodynamic heat environment . finally , by using the ansys program , the thermal vibration characters of the plate and missile body structures with different materials is analyzed 這一方法提高了熱振動的分析效率;第三,簡要的介紹了工程上計算氣動熟的估算方法及熱流密度計算的簡化公式,在不考慮燒蝕以及質(zhì)量引射等影響下,本文計算了幾種飛行條件下駐點和非駐點區(qū)的熱流密度分布,作為本論文算例的氣動加熱環(huán)境。
