| 1 | 用遗传算法进行多流股换热器网络综合的研究显示文摘建立了多流股换热器网络综合数学模型,该模型改进了文献中等温混合的不合理假设。多流股换热器网络综合问题本质上是一个混合整数非线性规划问题(MINLP),这类问题的非凸非线性的特性使得目标函数存在多个局部最优解。传统的基于梯度的搜索方法在处理这类问题时由于计算规模庞大且极易陷于局部最优解而不再适用,而遗传算法却为解决这类问题提供了很有希望的一个方向。因而对遗传算法求解多流股换热器网络综合问题进行了研究,提出了可以自动产生可行的多流股换热器网络的方法策略,最后通过两个例题说明所提方法是可行的。 | 魏关锋 姚平经 罗行 Roetzel Wilfried | 2003 | 高校化学工程学报2003，17，4： | 19 |
| 2 | Synthesis of Large-scale Multistream Heat Exchanger Networks Based on Stream Pseudo Temperature显示文摘Effective temperature level of stream, namely stream pseudo temperature, is determined by its actual temperature and heat transfer temperature difference contribution value. Heat transfer temperature difference con-tribution value of a stream depends on its heat transfer film coefficient, cost per unit heat transfer area, actual tem-perature, and so on. In the determination of the suitable heat transfer temperature difference contribution values of the stream, the total annual cost of multistream heat exchanger network (MSHEN) is regarded as an objective func-tion, and genetic/simulated annealing algorithm (GA/SA) is adopted for optimizing the heat transfer temperature difference contribution values of the stream. The stream pseudo temperatures are subsequently obtained. On the ba-sis of stream pseudo temperature, optimized MSHEN can be attained by the temperature-enthalpy (T-H) diagram method. This approach is characterized with fewer decision variables and higher feasibility of solutions. The calcu-lation efficiency of GA/SA can be remarkably enhanced by this approach and more probability is shown in search-ing the global optimum solution. Hence this approach is presented for solving industrial-sized MSHEN which is difficult to deal by traditional algorithm. Moreover, in the optimization of stream heat transfer temperature differ-ence contribution values, the effects of the stream temperature, the heat transfer film coefficient, and the construc-tion material of heat exchangers are considered, therefore this approach can be used to optimize and design heat exchanger network (HEN) with unequal heat transfer film coefficients and different of construction materials. The performance of the proposed approach has been demonstrated with three examples and the obtained solutions are compared with those available in literatures. The results show that the large-scale MSHEN synthesis problems can be solved to obtain good solutions with the modest computational effort. | 肖武 董宏光 李欣强 姚平经 罗行 Wilfried Roetzel | 2006 | Chinese Journal of Chemical Engineering2006，14，5： | 12 |

| 4 | 采用扩展温度振荡法测量超临界CO_2扁管内对流换热特性显示文摘As a natural working,fluid carbon dioxide (CO 2) has shown great potential in refrigeration and air conditioning industry. The heat transfer and pressure drop performance of supercritical CO 2 in pipes is necessary for gas-cooler design. This paper presents an experimental investigation of supercritical CO 2 heat transfer characteristics using temperature oscillation method.Considering the variable fluid temperature, an extended and more reasonable temperature oscillation model is built and used for heat transfer coefficient evaluation. The convective heat transfer coefficient of supercritical CO 2 flowing in an aluminum multi-channel flat pipe is measured for the first time.Experiments are performed under one typical pressure and temperature condition.The experimental setup and data acquisition as well as processing program are described in detail. New dimensionless heat transfer data in the form of Nusselt number via Reynolds number are given and analyzed.The results could be a good reference to gas-cooler design.The paper also supplies a general model or tool for determining local convective heat transfer coefficient which can be used more widely. | 张后雷 宣益民 Wilfried Roetzel | 2001 | 化工学报2001，52，7： | 3 |
