氨与乙醇高温自着火特性试验与动力学分析
Experimental and kinetic study on ignition Characteristics of ammonia/ethanol under high temperature
在当量比为0.5、1.0 和2.0、压力为0.14 和1.0 MPa、温度为1250~1980 K 条件下，利用激波管试验平台测量了氨/乙醇混合气的着火延迟期(IDT)，其中乙醇占总燃料的摩尔分数分别为：0、5%、10%和30%。提出了一个新的氨/乙醇模型(NH3-E)，验证了该模型能够可靠预测试验结果，并利用该模型进行了化学反应动力学分析。研究发现，乙醇对氨的着火延迟期起到显著的非线性促进作用，掺混比为5%(摩尔分数)的乙醇可以使氨/乙醇混合气…查看全部>>
The ignition delay time of ammonia/ethanol mixtures was studied by using shock tube at equivalent ratios of 0.5, 1.0 and 2.0, temperatures of 1250~1980 K, and pressures of 0.14 and 1.0 MPa, the molar fraction of ethanol in the total fuel is 0, 5%, 10% and 30%, respectively. A new ammonia/ethanol model (NH3-E) was proposed, which was proved to be able to predict the experimental results reliably, and the chemical reaction kinetics were performed based on it. …查看全部>>
