Boundary Layer Investigation at the Inlet of a Linear Blade Cascade

Abstract

Experimental investigation of the inlet boundary layers of a linear blade cascade is topic of this contribution. Experiments, that are present here, were performed as part of the research of the flow in the linear blade cascade and results will be used for the future evaluation of the end-wall losses in the cascade. Two configurations of the cascade were tested, which were defined by pitch/chord ratio (t/c). Based on outlet isentropic Reynolds number Re2is, several regimes of flow were investigated for each configuration. Measurements were performed by means of Pitot tube. Experimental results were compared with the theory of the boundary layer.
