Thecommon wall temperature assumption is used for stream-by-stream simulations. Itassumes that all the layers of a given type behave identically, and that, atany point along the exchanger, all the parting sheets (separating plates betweenlayers) have the same temperature. Forcommon wall temperature calculation the program uses only the number of layersof each stream, not the order in which they are arranged (the layer pattern orstacking pattern). It is effectively assumed that there is a “good” layerpattern, meeting the objective of minimal temperature variation through thedepth of the exchanger. Inorder to determine how good a layer pattern is, full layer by layercalculations should be performed. 以上这段如何翻译?请发言!
