| Abstract: | Heat transfer coefficients around labyrinth are the necessary boundary conditions and important parameters for the thermal analysis of construction in aircraft engines.Heat transfer experiments for straight-through conventional labyrinth,straight-through slant labyrinth and stepped conventional labyrinth are conducted under the conditions of different Reynolds numbers and gap widths.Effects of geometric and flow parameters on the heat transfer are considered physically.For the convenience of practical application,the relations are derived from the experimental data. |
