有机朗肯循环在长途卡车应用的废热回收方面显示出有希望的结果。该技术可以进一步提高当前卡车动力系统的效率。在这样的背景下，朗肯循环的动态模拟对于研究其启动和关闭阶段、控制策略及其限制非常重要。此类研究并不总是很容易在测试台上进行。本文讨论了在一维商业流体动力学模拟工具（GT-Power）下进行的朗肯循环的动态模拟。在对组件建模进行简要总结之后，本文重点讨论了模型的启动和初始化以及用于使仿真收敛的策略。解决了储罐尺寸和温度限制以说明模型的使用。
The Organic Rankine Cycle is showing promising results for waste heat recovery on long haul truck applications. This technology could further increase the efficiency of current truck powertrains. In such a context, the dynamic simulation of a Rankine cycle is found to be very important to study its starting and shutting down phases, control strategies and their limits. Such studies are not always easy to perform on a test bench. This paper deals with the dynamic simulation of a Rankine cycle done under a one dimension commercial fluid dynamic simulation tool (GT-Power). After a brief summary of the component modelling, the paper focuses on the starting and initialization of the model as well as the strategies applied to make the simulation converge. Tank sizing and temperature limitations are addressed to illustrate the use of the model.
