Ⅵ 化學工程和工藝專業英語(胡鳴)word版
In most of the operations encountered in the chemical and petroleum instries,one or more of the processes of momentum,heat,and mass transfer is involved.Thus,in the flow of a fluid adiabatic conditions through abed of granular particles,
Momentum transfer takes place between the fluid elements which are moving at different velocities||在大部份的操作方面在化學物質和石油業中遇到了,動力,熱和塊移動的一個或者更多個程序是 involved.Thus,在流經的流動斷熱的情況流動在床上粒狀粒子,動力移動在正在不同的速度移動的流動的元素之間發生.
Here,then,is an example of a process of simultaneous momentum and heat transfer in which the same fundamental mechanism is affecting both processes .fractional distillation and gas absorotion are frequently carried out in a packed column in which
In a very turbulent fluid the rates of transfer per unit area of both momentum and mass are high ;and as the pressure rises the rates of transfer of both momentum and mass increase together ,
It will now be shown not only that the process of momentum ,heat, and mass transfer are physically related ,but also that quantitative relations between them can be developed||在這里,然後,是相同的基本機制正在影響兩者的程序的同時動力和熱移動的程序的一個例子。微少的蒸餾和瓦斯 absorotion 時常在被包裝的專欄被實行在哪一個
在非常狂暴的液體中動力和塊的每單位區域移動的比率是高的 ;而且如壓力一起上升動力和大眾的增加的移動的比率 ,它現在將會被顯示不但動力,熱和塊的程序轉移身體上地被講 , 而且那數量的關系在他們之間能被發展||微少的蒸餾和瓦斯 absorotion 時常在被包裝的專欄被實行在哪一個在非常狂暴的液體中動力和塊的每單位區域移動的比率是高的 ;而且如壓力一起上升動力和大眾的增加移動的比率,它現在將會被顯示不但動力,熱和塊的程序轉移身體上地被講 , 而且那數量的關系在他們之間能被發展.
Another form of interaction between the transfer processes is responsible for the phenomenon of thermal diffusion in which a component in a mixture moves under the action of a temperature gradient .although these are important applications of thermal diffusion ,the magnitude of the effect is usually small relative to that arising from concentration gradients||在移動程序之間的另外形式的交互作用負責熱散布的現象在哪一個一個混合的一個成份在溫度傾斜度的行動之下移動。雖然這些是熱散布的重要申請 ,效果的大小通常對那是小的親戚從集中傾斜度出現||雖然這些是熱散布的重要申請 ,效果的大小通常對那是小的親戚從集中傾斜度出現.
When a fluid is flowing under streamline condition over a surface ,a forward component of velocity is superimposed on the random distribution of velocities of the molecules,
Thus if two adjacent layers of fluid are moving at different velocities ,there will be a tendency for the faster moving layer to be retarded and the slower moving layer to be accelerated by virtue of the continuous passage of molecules in each direction||當液體正在在一個表面上的流線情況之下流動的時候,一個速度的向前成份在分子的速度的任意分配上被重疊,如此如果二毗連液體的層正在不同的速度移動 ,比較快速的感人層將會有趨向是智能遲滯的和比較慢的感人層由於每個方向的分子的連續通道被加速 .
Similarly , the molecular motion will tend to rece any temperature gradient or any concentration gradient if fluid consists of a mixture of two or more components||如果液體有一個二或較多成份的混合,同樣地,分子的運動將會容易減少任何的溫度傾斜度或者任何的集中傾斜度.
If the motion of the fluid is turbulent , the transfer of fluid by eddy motion is superimposed on the molecular transfer process .in this case ,the rate of transfer to the surface will be a function of the degree of turbulence .when the fluid id highly turbulent, the rate of transfer by molecular motion will be negligible compared with that by eddy motion .for small degrees of turbulence the two may be of the same order||如果液體的運動是狂暴的 , 逆流運動的液體的移動在分子的移動程序上被重疊。在這情況,到表面的移動的比率將會是喧囂的程度的一個功能。||在這情況,到表面的移動比率將會是喧囂的程度一個功能。當流動的遺傳素質高度地狂暴的, 分子運動的移動的比率藉著逆流運動將會是可以忽略的與那相較。對於喧囂的小程度那二可能是有相同的次序的 .
In addition to momentum ,both heat and mass can be transferred either by molecular diffusion alone or by molecular diffusion combined with eddy diffusion .because the effects of eddy diffusion are generally far greater than those of the molecular diffusion ,is occurring. Thus the main resistance to the flow of heat or mass to a surface lies within the laminar sub-layer .
Thus the heat and mass transfer coefficients are much higher at high Reynolds ||除了動力之外,熱和塊能被轉移或被分子散布孤獨的或被被和逆流散布結合的分子散布。因為逆流散布的效果是通常遠比棒的那分子散布的那些 ,正在發生||因為逆流散布的效果是通常遠比棒的那分子散布的那些 ,正在發生. Thus the main resistance to the flow of heat or mass to a surface lies within the laminar sub-layer||如此對 laminar 子層裡面的一則表面的謊言對熱或塊的流程主要的抗拒 .
