Abstract

This work, presents a numerical study, using the CFD Fluent code, of a two-dimensional thrust reverser equipped with deflector doors to reverse the exhaust gas stream. The reverser is similar to those used in turbofan engines at high bypass ratio. The Reynolds averaged equations (RANS) were solved by using the turbulence standard k-ε model. Initially, the computer code FLUENT is validated by using a plane geometry for which the experimental data and the numerical results exist in the literature. The code is then applied to a reverser, which has an axisymmetric geometry. The results obtained made possible to detect all the physical phenomena present in the flow, in particular, those occurring at the areas of flow detachment/reattachment and to understand the behavior of the flow near the geometrical singularities of the reverser.
