摘要
讨论平面非牛顿流体(例如高粘度高含腊量的地下石油)在m>1时的径向流动.作者首先给出了问题的数学模型,它是退缩的自由边值问题.然后得到了该问题的近似问题古典解的存在唯一性.当油井边的压力梯度是常值函数时,该问题古典解的存在唯一性也得到了.
The radical flow of plane non-Newtonian is studied. The existence and uniqueness of the classical solution for its approximation problem is proved by a parabolic quasi-variational inequality. If the pressure gradient of the well is constent, the existence and uniqueness of the classical solution for itself is obtained.
