| 1 | Numerical analysis of reactive turbulent flow in the thrust chamber of RD-108 engine rocket显示文摘Combustion chamber modeling and simulation of the liquid propellant engine with kerosene as fuel and liquid oxygen as an oxidizer in the turbulent flow field are performed by CFD technique.The flow is modeled as Single-phase in steady state and using RNG k-ε turbulence model.Simulation results are validated by experimental data of thrust,special impulse and combustion chamber pressure.By comparing t.^wo reaction models of finite rate chemistry and frozen model with experimental data,it is concluded that finite rate chemistry has acceptable results.The optimum value of equivalence ratio(oxidizer to fuel ratio)per reaction and operational parameters of the engine which maximize thrust and special impulse are determined. | Seyed Reza Taghavi Mohammad Ali Dehnavi Ali Ghafouri | 2019 | Defence Technology(防务技术)2019，15，4： | 2 |
| 2 | 氧化锌-聚吡咯复合材料的介电性能和非线性特性(英文)显示文摘研究不同氧化锌(ZnO)含量的氧化锌-聚吡咯复合材料在200 Hz^5 MHz频率区间的非线性性能和频率特性。用热压法在130℃下制备样品。结果表明,当ZnO含量为70%时,击穿电压最小。击穿电压先从590 V降低到380 V,后从450 V增加到740 V,这是由于在晶界处没有聚吡咯。与击穿电压的变化不同,非线性系数随氧化锌含量的增加从4.2增加到9,这是由于随氧化锌含量的增加,晶界处的受主能级增加。电学参数如介电常数、介电损耗和样品的串联电阻对频率的依赖性很强,特别是在1 k Hz以下,这些参数随频率增加而下降,这与晶界上通过肖特基势垒的电荷传输有关。样品在1 kH z以下的高介电常数与晶界处的麦克斯韦-瓦格纳(Maxwell-Wagner)极化有关。在不同频率间隔区间存在不同的常数异常变化的现象,这与界面极化有关,是由于晶粒和晶界层结构的不同,导电性差异较大。 | Fariba TABRIZI Mojtaba PARHIZKAR Hassan BIDADI Mohammad GHAFOURI | 2018 | Transactions of Nonferrous Metals Society of China2018，28，7： | 2 |
