【摘要】：為了研究在太陽照射下不同時刻吸附床內(nèi)部溫度的變化情況以及不同冷卻條件對吸附床溫度場的影響,在充分了解太陽輻射強(qiáng)度變化規(guī)律的基礎(chǔ)上,建立了真空管吸附床的二維導(dǎo)熱模型,并采用FLUENT軟件對恒壁溫冷卻和空氣自然對流冷卻2種邊界條件下吸附床內(nèi)部的溫度變化進(jìn)行數(shù)值模擬研究,觀察其吸附床內(nèi)部溫度場分布.模擬結(jié)果表明:太陽照射下吸附床內(nèi)部的溫度分布明顯是不均勻的;恒壁溫冷卻和空氣自然對流冷卻2種邊界條件下吸附床內(nèi)部達(dá)到的最大溫度差值接近100℃.因此,可以得出恒壁溫的冷卻效果遠(yuǎn)比空氣自然對流冷卻的效果好;吸附床內(nèi)溫度的不均勻分布將不利于整個吸附床的吸附性能.
[Abstract]:In order to study the variation of internal temperature in adsorption bed at different times under solar irradiation and the influence of different cooling conditions on the temperature field of adsorption bed, the variation law of solar radiation intensity is fully understood. A two-dimensional heat conduction model for vacuum tube adsorption bed is established. The temperature variation in the adsorption bed under the boundary conditions of constant wall temperature cooling and air natural convection cooling is numerically simulated by FLUENT software. The temperature distribution in the adsorption bed was observed. The simulation results show that the temperature distribution in the adsorption bed under solar irradiation is obviously uneven, and the maximum temperature difference within the adsorption bed is close to 100 鈩，
