【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.更多还原

【Abstract】 The Oleinik classical linear method to was used discuss the axially symmetric stationary micro-fluid 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(0,x)=0,v(x,0)=v0(x),lim u(x,y)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.更多还原
