摘要

与传统的化学推进系统基于燃料在燃烧室中相对缓慢(亚音速)的受控燃烧不同,脉冲爆震发动机(PDEs)和旋转爆震发动机(RDEs)的运行过程分别基于燃料在脉冲爆震波和连续爆震波中的受控快速(超音速)燃烧。对于这种推进系统来说,最重要的问题之一是选择具有适当反应性和放热性的燃料,以实现持续和节能的运行过程。本文给出了含硼和含铝化合物(B, B \(_{{2}}\) H \(_{{6}}\), B \(_{{5}}\) H \(_{{9}}\), B \(_{{10}}\) H \(_{{14}}\), Al, AlH \(_{{3}}\), Al(C \(_{{2}}\) H \(_{{5}})_{{3}}\))和Al(CH \(_{{3}})_{{3}})\))在空气和水中的爆轰参数的热力学计算结果。结果表明,将所考虑的化合物用作以pde和rde为动力的空气和水呼吸运输车辆的燃料的潜在可行性。为了验证计算结果的可靠性,将二硼烷、铝和硝酸异丙基在空气中的爆轰参数与文献中已有的实验数据进行了比较。

Thermochemical study of the detonation properties of boron- and aluminum-containing compounds in air and water

Thermochemical study of the detonation properties of boron- and aluminum-containing compounds in air and water

Contrary to the conventional chemical propulsion systems based on the controlled relatively slow (subsonic) combustion of fuel in a combustor, the operation process in pulsed detonation engines (PDEs) and rotating detonation engines (RDEs) is based on the controlled fast (supersonic) combustion of fuel in pulsed and continuous detonation waves, respectively. One of the most important issues for such propulsion systems is the choice of fuel with proper reactivity and exothermicity required for a sustained and energy-efficient operation process. Presented in the paper are the results of thermodynamic calculations of the detonation parameters of boron- and aluminum-containing compounds (B, B\(_{{2}}\)H\(_{{6}}\), B\(_{{5}}\)H\(_{{9}}\), B\(_{{10}}\)H\(_{{14}}\), Al, AlH\(_{{3}}\), Al(C\(_{{2}}\)H\(_{{5}})_{{3}}\), and Al(CH\(_{{3}})_{{3}})\) in air and water. The results demonstrate the potential feasibility of using the considered compounds as fuels for both air- and water-breathing transportation vehicles powered with PDEs and RDEs. As a verification of the reliability of the calculated results, the detonation parameters of diborane, aluminum, and isopropyl nitrate in air were compared with experimental data available in the literature.

期刊介绍: Shock Waves provides a forum for presenting and discussing new results in all fields where shock and detonation phenomena play a role. The journal addresses physicists, engineers and applied mathematicians working on theoretical, experimental or numerical issues, including diagnostics and flow visualization. The research fields considered include, but are not limited to, aero- and gas dynamics, acoustics, physical chemistry, condensed matter and plasmas, with applications encompassing materials sciences, space sciences, geosciences, life sciences and medicine. Of particular interest are contributions which provide insights into fundamental aspects of the techniques that are relevant to more than one specific research community. The journal publishes scholarly research papers, invited review articles and short notes, as well as comments on papers already published in this journal. Occasionally concise meeting reports of interest to the Shock Waves community are published.
