Danica Basarić, Nilasis Chaudhuri

AI总结:

本文研究穿孔域上可压缩粘性热传导流体的低马赫数极限,证明其收敛到Oberbeck-Boussinesq近似,并利用弱-强唯一性原理获得强收敛。

摘要:

我们考虑描述可压缩、粘性和热传导流体在由微小孔洞穿孔的域上运动的Navier-Stokes-Fourier系统。首先,我们将Oberbeck-Boussinesq近似的一类耗散解识别为原始系统的低马赫数极限。其次,通过证明弱-强唯一性原理,我们在强解的生命周期上获得了对目标系统的强收敛。

英文摘要:

We consider the Navier-Stokes-Fourier system describing the motion of a compressible, viscous and heat-conducting fluid on a domain perforated by tiny holes. First, we identify a class of dissipative solutions to the Oberbeck-Boussinesq approximation as a low Mach number limit of the primitive system. Secondly, by proving the weak-strong uniqueness principle, we obtain strong convergence to the target system on the lifespan of the strong solution.
