摘要：
A prototype of hydraulic free piston engine (HFPE) is being designed and constructed by Jilin University to achieve direct hydraulic wheel-drive and replace the current hydraulic drivers. This paper is aimed at modeling and analyzing the scavenging system for the HFPE. Based on the prototype engine El 50, two stroke scavenging system for HFPE has been designed by analogy, the gas flow of HFPE during the scavenging process is simulated by using the commercial CFD software AVL FIRE. So some key scavenging parameters and flow field were obtained, the simulated results indicate that scavenging efficiency of loop scavenging system can meet the design requirement, it lies between perfect displacement and perfect mixing scavenging, and keeps decreasing while the operation frequency keeps increasing.
