| 摘 要： | 搭建了某型低速二冲程柴油机动力涡轮复合涡轮增压器的仿真模型,对动力涡轮并联模式展开联合优化匹配。以同时考虑系统热效率、系统总功率、柴油机功率、动力涡轮功率、涡轮增压器喘振裕度全面择优的方式,寻取最优匹配点。结果表明:动力涡轮与增压涡轮联合优化匹配后,在中高工况下旁通8.55%的排气用以驱动动力涡轮,额定工况下其输出功率为134.6 kW,占柴油机功率的3.19%,系统总功率提升1.02%。

| Abstract: | A simulation model of a power turbine compound turbocharger for a type of low-speed two-stroke diesel engine was set up, and combined optimization and matching was carried out on the parallel mode of the power turbine. A comprehensive selection method considering thermal efficiency of the system, system total power, the diesel engine power, the power of the power turbine, turbocharger surge margin was used to find the optimal matching point. The results show that after optimization and matching, under the medium and high load working condition, 8.55% of the exhaust gas is bypassed to drive the power turbine, the output power is 134.6 kW under the rated working condition, accounting for 3.19% of the diesel power, total power of the system is increased by 1.02%. |
