Abstract

Abstract: Complex traffic leads to a dynamic behavior of exhaust gas of vehicle. Therefore, a real operating of Organic Rankine Cycle (ORC), which is used for heat recovery, deviates the design working condition at most of time with a low operating efficiency. To solve the problem, a dynamic model of ORC system verified by experiment result was built. The dynamic behavior of the heat resource, divided into 6 modes, was used as an input of external condition to the developed model. The impact results of the step mass flow rate and the temperature of heat resource to the stability of system were analyzed. The results show that step time is appropriately positive linear to stable time. The initial mass flow rate is negative correlate to the stable time. The stable time is the quadric function of initial temperature, step span of temperature and mass flow rate. The research results show a useful meaning to understanding the dynamic behavior of ORC on vehicle and developing of control strategy.
