Asymptotic analysis of an $\varepsilon$-Stokes problem connecting Stokes and pressure-Poisson problems

Abstract

In this Note, we prepare an $\varepsilon$-Stokes problem connecting the Stokes problem and the corresponding pressure-Poisson equation using one parameter $\varepsilon>0$. We prove that the solution to the $\varepsilon$-Stokes problem, convergences as $\varepsilon$ tends to 0 or $\infty$ to the Stokes and pressure-Poisson problem, respectively.
