abstract

The effect of the nite extent of linear cascades on the unsteady pressure distribution due to the presence of moving bars is assessed by means of a numerical study. The height of a reference cascade made up of at plates has been changed to quantify its in uence. It is concluded that seven blades are enough to get rid of the contamination associated to the lateral walls of the cascade on the modulus of the unsteady pressure and that the resonant conditions of the cascade shall be avoided to improve its periodicity. The sidewall interference has been also studied for a representative low pressure turbine airfoil without signicantly modifying the conclusions obtained using at plates. The mode decomposition at the cascade exit shows also a reasonable matching with the periodic case.
