本文研究了具有无滑移边界条件的可压缩等熵Navier-Stokes方程的Prandtl边界层方程在小粘性极限下的局部适定性。在法向变量切向速度严格单调的假设下,我们采用Nash-Moser-Hormander迭代格式,进一步发展了[R.亚历山大等人,美国数学学会,DOI:S 0894 -0347(2014)00813-4],以获得方程在时间上的局部适定性。
In this paper, we consider the local well-posedness of the Prandtl boundary layer equations that describe the behavior of the boundary layer in the small viscosity limit of the compressible isentropic Navier--Stokes equations with nonslip boundary condition. Under the strictly monotonic assumption on the tangential velocity in the normal variable, we apply the Nash--Moser--Hormander iteration scheme and further develop the energy method introduced in [R. Alexander et al., J. Amer. Math. Soc., DOI:S0894-0347(2014)00813-4] to obtain the well-posedness of the equations locally in time.
