- 摘要:
- 为了建立凝胶推进剂管路流动模型．分析了凝胶推进剂模拟液在直圆管内的流 动特性．并对3种模拟液在第二和第三流动区内管路流阻的计算值与试验值进行了对比分析， 结果表明：在第二流动区，用幂律流变方程推导的压降公式计算值与试验值有较好的一致性； 在第三流动区。可以近似用牛顿流体压降公式计算管路流阻。此外还分析了压降的误差传播 系数．结果表明流变指数和管径的误差传播系数最大。
- Abstract:
- In order to set up the fluid model of the geUed propellants，the fluid characteristics of gelled propellant in the straight pipe were analyzed．The calculated pressure drop results of 3 type geHed propellant stimulants were compared through experiments．The comparison indicates：the pressure drop within the second fluid region Call be calculated by the equation educed from power law rheological equation of state．The loss in the third fluid region Can be calculated approximately by the Newtonian fluid pressure loss equation．The error diffusing coefficient was analyzed，the error diffusing coefficient of power law index and pipe diameter have the most important effect on pressure drop calculating value．
