絕熱假設 的英文怎麼說
中文拼音 [juérèjiǎshè]
絕熱假設
英文
adiabatic hypothesis-
A calculation example is used to get some figure. the effect of phase shift and attenuation in temperature fluctuation by thermal mass can be observed in these figures. the cfd simulation of the similar modeling is carried out, the result of the cfd simulation is similar to the calculation example
在前面工作的基礎上,本文作者還利用cfd軟體模擬了和前面模型中相似的情況,即只考慮室內蓄熱體的蓄熱作用,假設外圍護結構是絕熱的,得到的室內空氣溫度變化趨勢與算例所得到的是很相似的。The demonstration of heat - transfer measuring techniques and prospect of infrared thermal mapping techniques, main parts and performance indexes of a infrared camera, functional blocks and implementation of infrared processing software, experimental facility and measuring system of the wind tunnel has been made. the model emittance was experimentally determined and the three methods correcting directional emittance were compared. those problems of the infinite - slab model thickness and constant wall heat rates hypothesis, the determination of adiabatic wall temperature were discussed in a 1 - d heat conduction analysis
本文對紅外熱圖測熱技術與應用前景、紅外熱像儀主要部件與性能指標、紅外測熱數據處理軟體功能模塊與實現、風洞試驗設備與測量系統等進行了論述,測量了模型表面發射率並對發射率隨極角變化的三種修正方法進行了對比,對一維熱傳導分析中模型壁厚半無限假設、壁面熱流定常假設、絕熱壁溫選取等進行了探討。The wall is supposed insulate, indoor thermal mass is considered in the model. the control equation is very simple, but it is enough to study physical phenomena
該模型中假設圍護結構是絕熱的,只考慮了室內蓄熱材料的蓄熱作用,這樣得到的控制方程雖然比較簡單,但是對于研究簡單的物理現象已經足夠了。
