Steady state design and thermal characteristics of a gas turbine blade with lateral holes using finite element analysis

Abstract

Turbine blades are the separate components that make up the turbine section of a steam or gas turbine. The blades must transform the high-temperature, high-pressure gas that the combustor produces into energy. In gas turbines, the turbine blades are usually the limiting element. As gas temperatures rise, the amount of heat that reaches the blades will also grow dramatically, leading to their thermal failure. Because gas turbine blades must function in extremely high temperatures, cooling is crucial. After FEA simulation was conducted and radial perforations of 6, 9, and 12 were constructed to allow high-velocity cooling air to pass through, the cooling of the gas turbine blades was improved.
