Abstract

Transient heat transfer measurement techniques have long been used in two-dimensional stationary cascade tests designed to model turbine conditions used in Oxford. More recently, experiments studying some of the unsteady effects have been carried out using a rotating wake generator upstream of the rotor cascade. Currently work has concentrated on providing a fully three-dimensional rotating turbine stage. In an associated paper, the modifications necessary to accommodate this stage in the Oxford Isentropic Light Piston Tunnel are discussed. In this paper the developments necessary to permit the measurement of transient heat transfer under these rotating conditions are fully described.
