摘    要:利用Oleinik的经典线性化方法,讨论对称定常微流边界层方程{uu/x+vu/y=Udu/dx+v(y)uy]/y (ru)/x+(rv)/y=0,满足边界条件:u(0,y)=0,u(0,x)=0,v(x,0)=v0(x),lim u(x,y)y→∞=U(x)解的适定性问题.其中,v(y)>0是粘性系数,满足一定的限制条件.

关 键 词:微流边界层  粘性系数  存在性  唯一性

Abstract:The Oleinik classical linear method to was used discuss the axially symmetric stationary microfluid boundary layer equation: {u u/ x+v u/ y=Udu/dx+ v(y)uy] y (ru)/x+ (rv)/y=0,, satisfying the boundary conditions :u(0,Y)=0,u(O,x)=0,v(x,O)=v0(x),lim u y→∞(z,Y)=U(x) Where v(y) 〉 0 was the coefficient of viscosity satisfying some constraints. The existence and the uniqueness of the solution of boundary conditions for above equation were obtained.
Keywords:micro-fluid boundary layer  coefficient of viscosity  existence  uniqueness
