摘　　要：对3D打印旧砂通常使用热法进行回收,因此,需要对燃烧室内部流场有一个全面的了解。基于计算颗粒流体力学(CPFD)模型,设计了新型的燃烧室,将流场和燃烧模拟相结合,进行了燃烧室流场特性分析,包括内部两相流、温度场和燃烧产物,同时也验证了CPFD方法的可行性。Recycling 3D printed old sand usually uses thermal methods for recycling,therefore,it is necessary to have a comprehensive understanding of the flow field inside the combustion chamber.Based on the Computational Particle Fluid mechanics(CPFD)model,a new type of combustion chamber has been designed.The flow field and combustion simulation have been combined to analyze the flow field characteristics of the combustion chamber,including internal two-phase flow,temperature field,and combustion products.The feasibility of the CPFD method has also been verified.
