The cascade loss factor of the optimally designed cascades is significantly lower than that of the original cascades.

For the turbine stator cascade, the negative curving of blade can not improve the performance of the cascades as well, the total losses of straight cascade are the lowest.
Behind the tandem cascades, the variations of mean velocity and turbulence intensity along the tangential direction become more gentle than that behind the single-row cascade.
