We discuss the stabilization, via bubble functions, of a finite element method for stationary linearized incompressible Navier-Stokes equations. It is shown that the upwind bubbles can be used to obtain the SUPG stabilization. Furthermore, the diffusion-dominated case is discussed in more detail, and it is also shown that in this regime the bubbles reproduce the right parameter of SUPG.
