Comparative analysis of steady state heat transfer in a TBC and functionally graded air cooled gas turbine blade (Q970117)

Steady state heat transfer in an air-cooled functionally graded turbine blade is studied using a finite element code. A procedure based on analytical geometry is used to vary the volume fraction of the metal and ceramic as per a power law distribution over the blade domain. Temperature distribution of the same blade is computed and the two temperature distributions are compared. The results obtained from the FEM simulation with convection as the only external mechanism and no radiation are also discussed.
