runingTitle=null, highlight=null, articleAbstract=针对简化的熔混过程的熔态炸药黏性温升问题,在定常、层流假设下,基于柱坐标系下的Navier-Stokes方程,结合Ostwald-De Wale幂律流非牛顿本构模型,推导了熔铸炸药在搅拌条件下的速度场及剪切应力场解析表达式; 结合一维导热方程与黏性耗散通式,构建忽略自身化学能条件下的黏性温度场解析模型。借助FLUENT软件建立简化后的熔混数值模型,对速度及温度解析解与数值解进行了比对验证。结果表明,速度场和温度场的最大误差分别为1.2%和6.1%,解析解与数值结果基本一致,验证了理论模型和解析求解过程的正确性; 参数分析表明黏性温升与剪切应力与应变率张量分量的乘积及固含量大小正相关; 对于DNAN/HMX熔铸炸药体系,最大黏性温升出现在搅拌刀外侧位置; 当搅拌速率从120r/min提高到720r/min(增大了6倍),该最大温升在10s内增加了约16倍,达到3.6K。, authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

针对简化的熔混过程的熔态炸药黏性温升问题,在定常、层流假设下,基于柱坐标系下的Navier-Stokes方程,结合Ostwald-De Wale幂律流非牛顿本构模型,推导了熔铸炸药在搅拌条件下的速度场及剪切应力场解析表达式; 结合一维导热方程与黏性耗散通式,构建忽略自身化学能条件下的黏性温度场解析模型。借助FLUENT软件建立简化后的熔混数值模型,对速度及温度解析解与数值解进行了比对验证。结果表明,速度场和温度场的最大误差分别为1.2%和6.1%,解析解与数值结果基本一致,验证了理论模型和解析求解过程的正确性; 参数分析表明黏性温升与剪切应力与应变率张量分量的乘积及固含量大小正相关; 对于DNAN/HMX熔铸炸药体系,最大黏性温升出现在搅拌刀外侧位置; 当搅拌速率从120r/min提高到720r/min(增大了6倍),该最大温升在10s内增加了约16倍,达到3.6K。
