Investigation of buoyancy-driven heat transfer in H.P compressor disc cavities
conference contribution
posted on 2023-06-10, 00:37 authored by Seyed Mostafa FazeliSeyed Mostafa Fazeli, Vasudevan KanjirakkadVasudevan Kanjirakkad, Christopher LongA detailed knowledge of the flow structure and heat transfer within the rotor disc cavities is required for designing safe and efficient aero-engine compressors with a useful operating range. This paper presents the results from temperature field measurements obtained from the Multiple Cavity test facility at the University of Sussex. This emulates the secondary-air disc-cavity system in an aircraft engine high-pressure compressor. It comprises four externally heated disc-cavities and is supplied by a cool bore flow. The heat transfer is studied with the help of finite-element method using measured temperatures as boundary conditions. A validated 2D steady state heat conduction analysis methodology is also presented alongside Monte Carlo simulations. Results are presented for a range of values of Rossby number, Rotational and Axial Reynolds number and the buoyancy parameter.
