考虑光滑区域上二维粘性湖方程在Navier边界条件下的无粘极限问题,证明了具有Navier边界条件粘性湖方程的边界层在Sobolev空间中是非线性稳定的,验证了具有较弱强度的边界层的渐近展开的合理性.
t We consider the inviscid limit of the two-dimensional viscous lake equations when the Navier slip conditions are prescribed on the impermeable boundaries of the general regular domains. Our results show that the boundary layer of the viscous lake equations with Navier boundary is always nonlinearly stable in some Sobolev spacesand we justify an asymptotic expansion which involves a weak amplitude boundary layer, with the same thickness as in asymptotic theory and a linear behavior.
