具阀门梯度的平面流体的径向流动(英文)

The Radical Flow of Plane Fluid with the Yield Stress

研究了具阀门梯度的平面径向流动引起的一类自由边值问题 .首先给出了问题的数学模型 ,接着用等价的抛物拟变分不等式的研究 ,得出了该自由边值问题的古典解的存在唯一性 .

The authors consider a free boundary problem arised from the radical flow of plane Non Newtonian fluids with yield stress.The authors first give the mathematical model,i.e., the problem 1,and then obtain the existence and uniqueness of the classical solution by means of a parabolic quasi variational inequality.
