摘要
应用基元化学反应模型对一维氢氧混合气体爆轰波进行数值模拟。采用一端高温高压点火起爆的方式,模拟爆轰波的传播。对一维爆轰波的结构、传播特征以及各个化学组分的变化趋势进行了研究。通过将模拟的结果同国内外的研究结果进行对比,发现了一些规律,为多维爆轰波的数值模拟和脉冲爆轰发动机的研究奠定一定的基础。
The present paper involves one-dimensional simulation of detonation. The goal is to correctly understand the detonation structure, propagation characteristic. A high resolution method and an appropriate chemical reaction model play a main role to simulate detonation numerically. We mainly employed the ENO（essentially non-oscillatory） method to solve the reacting flow equations, including detailed chemical reaction model of the eight species and nineteen reactions for hydrogenoxygen mixture. Detailed results of detonation velocity, Von-Neumann spike, induction zone and dilution effect are carried out. We found that detailed chemical reaction model is an effective tool in detonation investigation. The present study establishes the groundwork for the further studies involved simulations of muhi-dimensional detonation and pulse detonation engines.
