In this paper, we prove the global existence and almost exponential decay of solutions for a Boussinesq approximation Bénard convection fluid. Compared with our previous paper [B. Guo, B. Xie, and L. Zeng, J. Differ. Equations 267, 2261–2283 (2019)], here the effect of the surface tension is neglected on the free surface. The analysis needs more higher regularity than the surface tension case.

在自由上界没有表面张力的Boussinesq方程的几乎指数衰减。

在本文中,我们证明了Boussinesq逼近Bénard对流流体的解的整体存在性和几乎指数衰减。与我们以前的论文相比[B. 郭,B。Xie,和L. Zeng,J。Differ。方程267,2261年至2283年(2019)],这里的表面张力的影响被忽略的自由表面上。分析需要比表面张力情况更高的规则性。
