    Abstract

    The influence of a combustor located just upstream13; of a nozzle guide vane cascade on the heat flux distribution to the nozzle guide vane was experimentally investigated. The surface temperature distribution around the connectivity cooled vane of the cascade was obtained by local the cascade firstly, in a low turbulence uniform hot gas stream, secondly in a high turbulence, uniform hot gas stream and thirdly in a high turbulence, non-uniform hot gas stream present just downstream of the combustor can be accounted for by the prevailing turbulence level measured at cascade inlet in cold-flow conditions and the average gas temperature at the cascade inlet.
