摘要: 首先, 利用微分不等式技术给出双向流动介质在牛顿冷却边界条件下关于温度的L4范数和解的先验估计; 其次, 利用解的先验估计并设置
适当的能量函数, 证明半无限管道中解随空间变量代数式衰减.

关键词: 双向流动介质, 空间性质, 能量分析

Abstract: Firstly, by using differential inequality techniques, we gave  a prior estimate of the L4 norm  and solution of temperature for bidirectional flow media under the Newtonian cooling boundary conditions. Secondly, by using a prior estimate of the solution and setting an appropriate energy function, we proved that the solutions decayed algebraically with spatial variable in a semi-infinite pipe.

Key words: bidispersive flow, spatial property, energy analysis
