Turbine performance increases through increasing turbine inlet gas temperature which can result in reduced turbine durability. Currently the design practices employed by the major OEM's for cooled turbine airfoils are generally very empirical in nature and can easily miss important physical behavior… More

The drumbeat for higher efficiency gas turbine engines is driving new designs capable of operating at higher temperatures and pressure ratios, in fewer stages, and with higher airfoil loads. These conditions pose a great challenge for turbomachinery designers. They must now accurately predict… More
