菜鸟求助盖德的高手们翻译一段论文摘要？ 大四了 毕业设计前得翻译一段论文，但是很菜，自己尽力了，能用的都用上了，能做的都做了，可是觉得还是翻译的不沾边儿，早就知道盖德的高手多，求求盖德的各位大哥大姐，帮帮忙，翻译一下摘要，尽量专业一些，不胜感激。 HEAT EXCHANGER DESIGN TARGETS FOR MINIMUM AREA AND COST K. MURALIKRISHNA and U. V. SHENOY Department of Chemical Engineering and Computer Aided Design Centre, Indian Institute of Technology, Bombay, India A methodology is proposed to determine the feasible region for shell and tube heat exchanger designs on a pressure drop diagram. By accounting for operating as well as geometrical constraints, the feasible region is defined so as to eliminate trial-and-error during the design activity. Every point on this plot of shellside versus tubeside pressure drop corresponds to a unique design in terms of tube length, shell diameter and baffle spacing. Furthermore, curves may be plotted for designs corresponding to a specified heat exchange area or a given total annual cost. Such curves permit screening of various design options prior to detailed rating of the exchangers, and allow heat exchanger design targets to be established for minimum area or cost. The area target ensures an exchanger of the smallest size with minimum capital cost, whereas the cost target yields the optimum pressure drops accounting for the tradeoff between power consumption and heat exchanger area. The methodology is equation-based and can be conveniently implemented on a computer. Keywords : shell and tube heat exchangers; cost targeting; cost-optimal design; minimum area design; capital±energy tradeoff; pressure drop diagram 查看更多10个回答 . 3人已关注
