Numerical Calculation of Aerodynamic Shape of an Axial Turbine Blade

Abstract

Aerodynamic characteristics, structural integrity, vibration elements, combustion, cooling, acoustics, and environmental impact are all active research and development topics in gas turbine design. On the other hand, turbine aerodynamics is a challenge due to high inlet gas temperature, secondary flow, separation, and transonic flow, as well as their interactions. Numerical methods and rising computational power have aided turbomachinery design in recent decades. With their increasing ability to predict flow features, CFD tools have become integral to the design process. Initially, the project was about calculating or measuring the efficiency of the blade by using the numerical method or CFD simulation. Based on the step of the CFD modelling, which includes the geometry, solver, and post processes. One of the most crucial parts was the designing phase which determined the obvious result to export to the geometry that needed to be in the perfect model to be mesh. At the end of this study, the efficiency calculation was determined based on the result achieved and the following steps, such as the pressure drop. The high-pressure drop may cause a cavity in the finished model, and better get the lower-pressure drop to show a good blade profile performance.
