顯熱交換 的英文怎麼說
中文拼音 [xiǎnrèjiāohuàn]
顯熱交換
英文
sensible heat transfer-
Compared with the existing techniques for enhancing heat transfer by adding millimeter and / or micrometer - sized particles in fluids, nanofluids appear to be ideally suited for practical application with incurring little or no penalty in pressure drop because the nanoparticles are so small that the nanofiuid behaves like a pure fluid
在液體中添迦納米粒子，可以顯著增加液體的導熱系數，提高熱交換系統的傳熱性能，而且由於納米粒子的小尺寸效應，其行為接近於液體分子，不會象毫米或微米級粒子易產生磨損或堵塞等不良結果。Similarly, the net radiation on a cloudy day is mainly used up evaporation of soil. the integrated value of soil heat flux is negative on a cloudy day and that shows the soil emits the heat, which is different on a clear day. in short, average latent, sensible and soil heat flux is 67 %, 21 % and 6 % of net radiation respectively
在裸地下墊面時，晴天潛熱佔到凈輻射的60 ，顯熱交換只佔到19 ，在陰天凈輻射同樣主要消耗于土壤蒸發，與晴天不同的是在陰天土壤熱通量積分值小於零，表明土壤在向外釋放熱量；平均狀況下，潛熱、顯熱和土壤熱通分別佔到凈輻射的67 、 21和6 。( 3 ) compared with bare soil, income of net radiation declined, apparent heat weakened and latent heat exchange were almost disappeared on the soil surface with film
（ 3 ）薄膜覆蓋于土壤表面后，與未覆蓋的土壤相比，地表凈輻射r _ n收入下降，顯熱交換p減弱，潛熱交換le趨于零。Analyses experimental results with classical heat and mass transfer theory, and indicates that when these parameters change, the latent heat efficiency changes much more than the sensible heat efficiency
利用經典傳熱、傳質理論對實驗結果進行了分析，指出當上述因素發生變化時，全熱交換器潛熱交換效率受到的影響大於顯熱交換效率。Soil heat flux from atmosphere to soil is about 5 % of net radiation on a clear and cloudy day and soil discharge energy to atmosphere on a rainy day above the same field. in brief, average latent heat, sensible heat and soil heat flux is 40 %. 50 % and 10 % of net radiation respectively
在春小麥下墊面，晴天能量主要消耗于農田蒸散，而在陰天顯熱交換大於農田蒸散耗熱；在晴天和陰天大氣向土壤的能量傳輸均維持在凈輻射的5左右，雨天時，土壤熱通量為負值。Its main function is to complete heat exchange in technological process and reuse remaining heat, and its quality plays an important role in the investment in industrial process, power consumption and safe economic operation etc. as a new energy - saving equipment, the tubular heat exchanger with longitudinal flow of the shellside fluid ( thelfsf ) has many remarkable advantages
其主要作用是完成工藝過程的熱量交換和余熱利用，其性能的優劣對工業過程的投資、能耗及安全經濟運行等起著重要作用。縱流殼程換熱設備作為新一代節能降耗設備，具有優良的防流體誘導振動性能、傳熱性能好、流體流動阻力小、抗結垢能力強、使用壽命長、重量輕、節約材料等顯著優點。Single - layer model is convenient to apply but the unclear relationship between radiative and aerodynamic temperatures is still a bottleneck in this field. a new method was developed to derive reliable surface heat fluxes from radiative temperature viewed from arbitrary zenith angle. aerodynamic and radiative temperatures are connected through a so - called optimum component fraction ( ocf ) parameter - the fraction of vegetation in the field of view when the two temperatures are equivalent in oblique viewing
該方法利用表面熱輻射方向性和顯熱通量都是源於土壤和植被溫度的貢獻這一共同點，發現在一定傾斜角度的觀測下，視場中植被與土壤的比例可以較好地反映植被和土壤與大氣進行湍流熱交換的貢獻率，所以稱該方法為最佳組分面積比法，用最佳組分面積比可以將任意角度下觀測到的輻射溫度訂正為空氣動力學溫度，經過地面和遙感數據驗證表明，用該方法計算的通量精度高於普通的單層模型。Finned tube is used to product various of efficient heat exchanger devices, especially in the remaining heat using area
翅片管用於製造各種高效率的熱交換器，特別在余熱利用方面大顯神通。A very much different fluxes model was suggested for remote sensing estimation, which takes account of the effects of advections in vertically or horizontally anisothermal vegetations. the inter - exchange of heat can result in lower total sensible heat flux and higher total latent heat flux of the considered areas. this method is designed technically for the simulations of pixel, is a try of new generation effluxes model
針對遙感基於像元計算的特點，提出一種全新的通量計算方法，模型的結構和思路專為遙感像元面上計算的特點而設計，主要考慮由地表非均勻和不連續性引起的像元內部熱量交換? ?局地微平流對顯熱和潛熱通量的影響，驗證表明，這種考慮平流的非均勻模型可以較好地模擬地表非均勻狀態下的熱量通量。The calculated result shows that there are significant influences of heat transfer on the engine ' s transient performance, and the component efficiency loss caused by tip clearance changes can not be ignored
通過計算分析，零部件與氣流之間的熱交換對發動機過渡過程性能有顯著影響；過渡過程葉尖間隙的變化引起的部件效率損失是不容忽視的。分享友人
