Abstract: The paper deals with the experimental and numerical research of flows through prismatic turbine cascade in transonic regimes. The primary goal is to evaluate the influence of the non-uniformity of the inlet velocity profile to the spanwise distribution of energy losses. The numerical simulation with inlet velocity profile corresponding to the parameters of the flow in high speed wind tunnel in Nov´y Kn´ın is compared to the experimental data. Next, the simulation assuming different inlet velocity profiles are used to evaluate the effect of the boundary layer in front of the cascade to the span-wise distribution of energy losses.
