摘要

Abstract > For the first time, mesoscale simulations of shocked explosives are validated with hot spot temperature data. Following recent experiments, we simulate a 25?μm aluminum flyer impacting a powder bed of octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine (HMX) with an initial speed of 1.4 to 3.6?km?s ?1 . The powder bed has a density of 0.56?g?cm 3 , or 29?% crystal density, and an average grain size of 4? <mat:math altimg="urn:x-wiley:07213115:media:prep201900195:prep201900195-math-0001" wiley:location="equation/prep201900195-math-0001.png"> <mat:mi>μ</mat:mi> </mat:math> m. Simulations are performed in the multi‐physics code, ALE3D. We employ a comprehensive HMX material model that accounts for the chemistry, unreacted and product equation‐of‐states (EOSs), elastic‐plastic response, as well as melting and melt viscosity. Simulations show compaction, reaction, and gas jetting during the initial stages of shock in the powder bed. Shock reflection at the glass window interface increases hot spot temperatures in HMX product gas in excess of 7000?K at higher impact speeds which is readily observable using pyrometry techniques. We extract a temperature histogram from simulations at discrete times, using it to calculate an effective emission spectrum and effective temperature, T <sub>eff</sub> , for comparison to data. Simple T‐ and T 4 ‐based methods inadequately weight the higher temperature regions and result in a low T <sub>eff</sub> that is in poor agreement with data. However, calculating T <sub>eff</sub> based on Planck's Law with a gray body assumption demonstrates good agreement with hot spot temperature data. A modified Arrhenius model is fit to the normalized reaction rates predicted by mesoscale simulations and inferred temperatures range from 1544?K to 1779?K; these temperatures are approximately 4x lower than the peak hot spot temperatures but 2‐3x higher than the bulk shock temperatures. The agreement with experimental results validates our mesoscale simulations as useful tools for elucidating the role of hot spot mechanisms in the shock initiation of heterogeneous explosives. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 首次，震动爆炸物的Messcale模拟验证了热点温度数据。近期实验后，我们模拟了25℃的铝传单，影响八烷基-1,3,5,7-四硝基-1,3,5,7-四胞嘧啶（HMX）的粉末床，初始速度为1.4至3.6？ km？s. ？1 </ sup> 。粉末床的密度为0.56Ω·克？cm 3 </ sup> ，或29倍晶体密度，平均晶粒尺寸为4？ <MAT：MATH ALTIMG =“URN：X-Wiley：07213115：Media：Prep201900195：Prep201900195-Math-0001”Wiley：Location =“等式/ Prep201900195-Math-0001.png”> <MAT：MI>μ</ MAT：MI> </ mat：math> m。在多物理代码ALE3D中执行模拟。我们采用了一个综合的HMX材料模型，用于化学，未反应和产品方程（eoss），弹性塑料响应以及熔化和熔体粘度。仿真显示在粉末床上休克初始阶段的压实，反应和气体喷射。玻璃窗界面处的冲击反射将HMX产品气体中的热点温度提高超过7000 kK，在较高的冲击速度下，使用热测定技术容易观察。我们在离散时间下从模拟中提取温度直方图，使用它来计算有效的发射光谱和有效温度T. <sub> eff </ sub> ，与数据相比。简单的t-和t 4 </ sup> 基于较高的温度区域，重量较高的方法，并导致低于T. <sub> eff </ sub> 这是与数据似乎不佳。但是，计算t <sub> eff </ sub> 基于Planck的灰色身体假设的法律，展示了与热点温度数据的良好一致性。修改的Arhenius模型适合Messcale模拟预测的归一化反应速率，并推断出1544 k至1779的温度范围内的温度;这些温度比峰值热点温度低约4倍，但比散装休克温度高2-3倍。与实验结果的协议验证了我们的Messcale模拟作为阐明热点机制在异构爆炸物的冲击发起中的有用工具。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-29946/'>《Propellants, Explosives, Pyrotechnics》</a> <b style="margin: 0 2px;">|</b><span>2020年第2期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Springer H.
