本文建立了存在热漏的换热过程模型,应用最优控制理论导出了过程熵产生最小时热、冷流体温度间最优关系。结果表明,热漏对换热过程熵产生最小时热、冷流体温度有较大影响,热流率一定的传热策略要优于热流体温度一定的传热策略,本文的研究对于换热过程的最优设计与运行有一定的理论指导意义。 In this paper, a heat exchange heat transfer process model with heat leak is established. The optimal relationship between the minimum hourly heat and the cold fluid temperature is derived using the optimal control theory. The results show that the heat leak has a great influence on the minimum hourly heat and the temperature of the cold fluid during the heat transfer process. The heat transfer strategy with a certain heat flux rate is better than the certain heat transfer strategy with the heat fluid temperature. In this paper, Optimal design and operation of a certain theoretical guidance.
