为了研究各种因素对旋转式微波辅助再生柴油机颗粒过滤器（MRDPF）连续再生性能的影响，建立了旋转式微波辅助再生柴油机颗粒过滤器（MRDPF）的再生数学模型和场协同模型，并基于三种不同的湍流模型分析了旋转式MRDPF的湍流动能分布和压力分布。结果表明，RNG k-ε模型更适合旋转式MRDPF的模拟，适当增加过滤单元数量、氧含量和废气温度可以改善旋转式MRDPF的再生性能。废气入口流速可以改变速度场与温度场的协同程度，协同程度高的区域主要集中在过滤单元的上部和中部。此外，再生阶段流速达到0.3m/s时，过滤单元的现场协同度和再生效率均较好，再生优化面积比和最大再生效率分别为0.51%和91%。该工作为优化旋转式MRDPF的连续再生性能提供了很好的参考价值。
In order to investigate effects of various factors on continuous regeneration performance of a rotary microwave-assisted regeneration diesel particulate filter (MRDPF), a regeneration mathematical model and a field synergy model of the rotary MRDPF are developed, and turbulent kinetic energy distribution and pressure distribution of the rotary MRDPF based on three different turbulence models are analyzed. The results indicate that the RNG k-ε model is more suitable for simulation of the rotary MRDPF and appropriate increment of filter unit number, oxygen content and exhaust gas temperature can result in the regeneration performance improvement of the rotary MRDPF. Inlet flow velocity of exhaust gas can change synergy degree between the velocity field and the temperature field and high synergy area is mainly concentrated in the upper and central parts of the filter unit. Moreover, field synergy degree and regeneration efficiency of the filter unit are both better when the flow velocity reaches 0.3 m/s during regeneration phase, where regeneration optimized area ratio and maximum regeneration efficiency are 0.51 and 91%, respectively. This work provides great reference values for optimizing the continuous regeneration performance of the rotary MRDPF.
