In this talk I will discuss the stabilization techniques for parametrized viscous flows in a reduced basis setting. Offlineonline computational splitting is implemented and offlineonly, offlineonline stabilization are compared (as well as without stabilization approach). Different test cases are illustrated and several stabilization classical approaches (SUPG, GLS, BrezziPitkaranta, Franca, Hughes, etc) are recast into a parametric reduced order setting. This approach is then compared with the other supremizer options to guarantee the approximation stability by lifting the corresponding parametric infsup constant. The goal is twofold: to guarantee stable parametrized viscous flows with increasing Reynolds numbers and to guarantee online computational savings by reducing the dimension of the online reduced basis system.
