Flow simulation and geometry optimization of gas turbine combustion camber

A numerical simulation system for the three-dimensional gas turbine combustion camber internal flow was established,based on the advanced computational fluid dynamics commercial software STAR-CD and real combustion camber geometry with detailed features represented. Numerical results for the flow inside an original design of the combustor were obtained and the main problems of the flow field were discussed. Special measures were taken to improve the flow structure inside the combustor. Numerical experiments show that those measures are very effective and the modified design is much better than the original design. The numerical analytic system for the flow inside the combustor proved to be a powerful tool for the optimal design of the combustion camber.
