Hubsection of GT compressor first stage rotor blade: mesh generation.

This paper proposes a framework for an efficient integration between geometric modeling program and analysis tool for a coming automated aerodynamic design optimization mission. This demand can be addressed by using both in-house codes and commercial software which have the good ability of live-link and efficient integration. In this study, the mathematical modeling of a turbomachinery airfoil shape using NURBS curve is carried out within MATLAB R2010b, and then is automatically taken to COMSOL Multiphysics 4.2a for two-dimensional numerical simulation of the flow around the airfoil. The results demonstrate the high ability of COMSOL to be a really helpful analysis tool in an automated design optimization loop, including geometric models, fluid/structural analysis results, field experimental data and an optimization program.
