Abstract
[fr] Since numerical boosters design tends to be the most realistic as possible, more and more details are added in the computational fluid dynamics simulations. Among that, the variable bleed valves opening can represent a technological challenge. Usually, boosters design is not affected by them since the operating points where they are susceptible to act are not included in the design points. But recently, experiments showed that they may have an influence on the life of the last rotating stage blades in the low-pressure compressor. This work focus on their CFD modelization using two differents methods.
