Labyrinth Seal of Aircraft Turbine Engine Air Flow Calculation at High Viscosity
This paper describes a CFD calculation of aircraft turbine engine labyrinth seal. The geometry of labyrinth seal shows that the air flow is very viscous. Based on the CFD calculation it was prepared some analysis of Reynolds numbers, Mach numbers and total temperature with different rotational speeds. Based on this analysis it is possible to improve the standard design steps of labyrinth seals of aircraft turbine engines. It should be helpful for thermodynamic and aircraft engineers.
