On similarity solutions for boundary layer flows with prescribed heat flux

B. Brighi, J. -D. Hoernel

摘要:

研究了在$\mathbb{R}^+$上的三阶非线性自治微分方程$f'''+(m+2)ff''-(2m+1)f'^2=0$在边界条件$f(0)=-γ$、$f'(\infty)=0$和$f''(0)=-1$下解的存在性、唯一性和性态.这个问题出现时,寻找相似的解决方案,边界层流动与指定的热通量。为了研究解,我们使用一些直接的方法以及爆破坐标,以获得一个平面动力系统。

英文摘要:

This paper is concerned with existence, uniqueness and behavior of the solutions of the autonomous third order nonlinear differential equation $f'''+(m+2)ff''-(2m+1)f'^2=0$ on $\mathbb{R}^+$ with the boundary conditions $f(0)=-γ$, $f'(\infty)=0$ and $f''(0)=-1$. This problem arises when looking for similarity solutions for boundary layer flows with prescribed heat flux. To study solutions we use some direct approach as well as blowing-up coordinates to obtain a plane dynamical system.
