- Abstract
- The optimization process was used to optimize the receiver hole to improve the discharge coefficient and temperature drop effectiveness of gas turbine pre-swirl system by using CFD analysis. In the optimization process, three design variables were selected through the geometry and sensitivity analysis, two objective functions were important performance evaluation indicators of secondary cooling air system. The Optimal Space-Filling Design method was used to get the experimental points and Kriging method to create the response surface, candidate points were created by Multi-Objective Genetic Algorithm method through the response surface. The optimization process was finished when the deviation between predicted result and CFD result was less than 0.1 %. Comparison with initial model, optimized model improved the secondary cooling performance and reduced the flow losses of the system. According to the final results from optimization process, the discharge coefficient and temperature drop effectiveness of the optimized model were increased 1.778 % and 5.335 % than initial model, respectively.
