| Abstract: | Heat transfer of
rows on leading edge of turbine blade was studied experimentally. Minimum blowing rate with
no ingress of gas into cavity,and local heat transfer coefficients on the leading edge and the flat
side wall were measured. The influences of mainstream Reynolds number and blowing rate on
heat transfer coefficients were described. The test parameters are the mainstream Reynolds
number from 42 000 to 127 000 and blowing rate from 0 8 to 2 0. |
