  • The numerical investigation on the effect of bowed blade to the aerodynamic performance of a two-stage low pressure turbine was presented.By analyzing the flow field of the bowed blade of different bowed-angle and bowed-type,the result is:under the stage circumstances,bowed blade design should match the real load condition;for target turbine,the first stage stator with positive bowed type and the second stage stator with negative bowed type have the best aerodynamic performance;compared to the symmetry bowed blade,J bowed type improves load distribution of the stage and reduces the secondary flow loss and shock wave loss;further more,the blade with small bowed-angle which has better pressure distribution and less entropy production of the mid-flow passage is superior to the big one.
