In this paper the turbine cascade of the ground heavy duty gas turbine designed by GE company has been redesigned to adapt middle and low heat value fuel by one dimensional and quasi three-dimensional calculation and analysis. To change the heat value of fuel brings the change of flow mass, which leads to a change in aerodynamic performance. The results of the redesign show that the general parameters...
The internal cooling effects on a stator blade in a turbine was simulated. The results showed that the thermal barrier coating (TBC) not only lowered the temperature but also made the temperature distribution more uniform, which could decrease the thermal stress and prolong the blade using life to a great extent. The FORTRAN code was used to solve the internal heat transfer coefficient and the temperature...
