As labyrinth seals with honeycomb facings become more usual, the present paper reveals part of the honeycomb parameters which have an influence on the temperature drop across the seal and the temperature distribution along the rotor and the stator. Numerical and first experimental analyses with varying honeycomb parameters, pressure ratios and seal clearances, typical for engine operating conditions, have been carried out on a non-rotating setup in order to exclude other influencing parameters, such as windage heating. As expected, the numerical analyse shows that the honeycomb diameter, the honeycomb height and the seal clearance are of great importance for the temperature distribution of the rotor and the stator and the temperature drop across the seal.
