摘要

研究了在薄域Ω ε {\Omega ^ {\varepsilon}}上具有非线性Tresca摩擦型的广义非牛顿流体的三维边值问题。研究了流体域一维趋近于零时的渐近行为。我们证明了流体的速度和压力的一些弱收敛性。然后得到二维区域的极限问题和具体的Reynolds方程。

Calculation of Reynolds equation for the generalized non-Newtonian fluids and its asymptotic behavior in a thin domain

Three-dimensional boundary-value problem describing a generalized non-Newtonian fluid with nonlinear Tresca friction type in a thin domain Ω ε

{\Omega^{\varepsilon}}
