摘要

本文基于计算粒子流体动力学（CPFD）模型，设计了一种输出功率为 5 吨/小时的新型燃烧器。流场模拟与燃烧模拟相结合，分析了内部两相流、温度场和燃烧产物。对燃烧器结构进行了优化。模拟结果表明，在原有结构下，废砂的回收效率和燃烧器的能量利用率都有所提高。砂床对流场特性有显著影响。将砂床高度增加 50 毫米，燃烧器内的颗粒温度升高，可提高废砂回收效率。提高了天然气的利用率，提高了经济效益。CPFD 方法的可行性可以非常有效地模拟燃烧器内的流场特性。

Numerical simulation and improvement of combustor structure in 3D printed sand recycling system

In this paper, a new combustor with an output of 5 t/h is designed based on a computational particle fluid dynamics (CPFD) model. The flow field simulation is combined with the combustion simulation to analyze the internal two-phase flow, temperature field, and combustion products. The combustor structure was optimized. The simulation results show that the recovery efficiency of the waste sand and the energy utilization of the combustor can be improved under the original structure. The sand bed has a significant effect on flow field characteristics. The increase in particle temperature in the combustor increases the efficiency of waste sand recovery by increasing the height of the sand bed by 50 mm. The utilization rate of natural gas is increased and the economic efficiency is improved. The feasibility of the CPFD method can simulate the flow field characteristics inside the combustor very effectively.
