| Abstract: | This paper presents an automated computer aid design optimization program for aerodynamic and heat transfer optimization of 2D internal cooling gas turbine blades.Parametric geometry models were developed with analytic function methods.The suction surface and pressure surface are presented by a series of quintic splines,the leading edge geometry and the trailing edge geometry were represented by circular arc which helps to maintain a smooth geometry connection at the end points of the pressure side and the ... |
| Keywords: | cooling turbine blade multi-objective optimization KS function parametric design coupled aero-thermal analysis |
