Numerical study of helium jet injection into channel with sudden expansion
Résumé
In the paper, results of the numerical study on the cross-flow helium jet injection into a channel with backward facing step (BFS) are presented. The simulations are performed under the conditions of high-enthalpy flow, which are similar to those of high speed flight. 2D and 3D numerical investigations were performed with ANSYS FLUENT 14.0. The objectives of the investigation are to study the flow structure in both 2D and 3D approaches and to find optimal conditions for air and helium mixing
