Abstract
The wake interaction problem in a turbo-machine has been simulated in a water table. The pressure distribution over a compressor blade during the passage of a wake shed by an upstream wake generator has been determined experimentally using specially developed piezo-electric pressure transducers. The results indicate that the theory developed by R. X. Meyer for wakes that are very thin with respect to the blade chord is generally valid. The theory has been extended to cover the case of wakes of finite thickness. The peak unsteady force amounted to at least 23% of the steady lift force assuming a steady lift coefficient of 1.
