MODELLING OF FLOW IN LINEAR BLADE CASCADE WITH THICK TRAILING EDGE AT A LOWER REYNOLDS NUMBER
Straka P., Příhoda J.
pages 930 - 933, full text

In this paper there are compared results of numerical simulation of compressible turbulent flow through low-pressure turbine blade cascade with relatively thick trailing edges for various physical models. Steady, unsteady, fully turbulent, transitional, two-dimensional and three-dimensional models are compared. Results show that: a) steady simulation gives an incorrect prediction of the boundary layer development, b) two-dimensional unsteady simulation leads to inaccurate prediction of the far wake development and c) only three-dimensional unsteady transitional simulation gives sufficiently accurate prediction. Results of numerical simulations are compared with the experimental data.
