At the same time , i discover that the number of the return air inlet has a little influecing and it can be neglected . when there is hot resource at upperside of the room , the hot jet and supply air jet together affecting . at the same lower part heat intensity , a utmost wind speed exist , the supply air speed lower , the more heat intensity on the upside , the less convecting transfer heat , whereas 對于上部有熱源的條件下,則其對流熱轉移量的變化關系是由熱射流與送風冷射流共同作用影響的,在下部熱源強度相同的條件下,存在一極限風速,在該風速以下,上部熱源強度越大,則對流熱轉移量越小,反之在該風速以上,上部熱源強度越大,則對流熱移量越大。

As the return of flow is being , one side the heat gain of higher zone will be lead back , on the other hand , the heat has been transmitted to upside also will return , so the heat gain will incr ease . the methods of using numerical simulating has been used to analyze the factors influecing convecting transfer heat in this paper 實際運行時由于空氣的回返,一方面會把上部的得熱帶回工作區,另一方面也會把下部已傳送上去的熱量又帶回,從而增加了下部的得熱量,本文就影響對流熱轉移量的因素利用數值模擬的方法做了一初步的研究。

In this paper , using phoenics software to compute and analyze the variety rule of the convecting transfer heat at the basis of computing and analyzing the temperature and velocity field of one underfloor supply air room with a focus hot source , and concluding that the number of the hot source and the supply air outlet > the intensity of the hot source and the volume of supply air will influence convecting transfer heat , and obtained its correlativity formula 本文針對一下部有集中熱源的地板送風空調小室,利用phoenics軟件,在計算分析小室內氣流的速度場及溫度場的基礎上,對對流熱轉移量的變化規律做了計算分析,最后得出對于下送風小室的對流熱轉移量與熱源的個數、送風口個數、熱源強度、送風量等因素有關,并且得出了其相關關系式。

That the earth has an iron - rich liquid core , sufficient energy to drive convection and a coriolis force to twist the convecting fluid are primary reasons why the geodynamo has sustained itself for billions of years 地球擁有富含鐵的液態核心、有足夠的能量驅動對流,并具有科氏力可使對流的流體扭轉,這些是地球發電機之所以能自我維持數十億年的主要原因。
