- overall isentropic efficiency 总等熵效率
- Velocity circulations at the trailing edges of each blade-row are optimized for overall maximization of total pressure ratio and isentropic efficiency. 优化目标为总压比和绝热效率最大,决策变量为转子和静子叶排尾缘速度环量。
- It is seen that the time-averaged unsteady isentropic efficiency is lower than that from steady analysis. 在此基础上详细分析了流场特性随时间的变化,发现时均非定常等熵效率小于相应的定常等熵效率;
- The detailed information of flow field shows that the numerical results agree well with experiment data.The isentropic efficiency was improved 0.395 percent. 通过对涡轮流场细节的分析表明,计算结果与试验数据吻合的较好,优化后的涡轮绝热效率提高了0.;395%25。
- By increasing isentropic efficiency of compressor and turbo-expander, air refrigeration should increase its energy efficiency and improve its application to air conditioning. 因此,提高它们的绝热效率是使空气制冷在空调领域得以推广应用的关键技术。
