Numerical study on the influence of coolant temperature, pressure, and thermal barrier coating thickness on heat transfer in high-pressure blades

•Influence of various factors on the actual gas turbine blade was investigated.•High thermal stress is at platform, leading edge, and leading and trailing tip.•Low-pressure leads to lack of supplying coolant for trailing passage, while at high-pressure, film cooling lift-off at leading tip reduces c...
