Description: 

As gas turbine operating temperatures increase, thermal management methods become critical. Designing turbine blades and vanes with sufficient cooling is necessary to avoid blade damage and performance degradation. Along with the importance of knowing bulk fluid and solid temperatures, it is also important to characterize complex flow features as well as temperature uniformity and hot-spots. Additionally, blade-row interaction such as wake impingement and thermal stacking must be considered.

Multi-physics analysis methods can be used in the design phase to avoid thermal management problems for failure analysis and redesign. Due to the complex physics involved, it is critical that high quality computational grids are used along with first-principles, physics based models. Conformal meshing, near-wall boundary layer grids, and resolution of thermal gradients are just some of the necessary mesh considerations.

Turbomachinery simulation specialists at CD-adapco offer a webcast focusing on blade cooling and thermal management. The material discusses physics models within STAR-CCM+ that are used to accurately model conjugate heat transfer and unsteady turbomachinery flows. Demonstrations show unique meshing capabilities that quickly produce high quality grids and how the entire process from CAD to solution is executed from within a single software platform.
