Safe and efficient operation of gas turbines relies on cooling the turbine blades via internal air channels. Simulation tools have long been used to predict metal temperatures and blade loads, but the process is often time-consuming and complex, with many stages and data transfers between different tools.
This white paper details how a single integrated platform predicting both fluid and solid temperatures in the blade is a step up from the traditional design workflow. This combined conjugate heat transfer/ computational fluid dynamics (CHT/CFD) workflow has enabled Siemens Energy to progress their designs beyond the limitations of conventional approaches. It increases both speed of simulations and accuracy of results and allows Siemens Energy to improve gas turbine blade cooling.

The goal in turbine blade cooling simulation is to predict metal temperatures throughout the blade, as well as the aerodynamic loads and metal stresses. The standard process for this usually involves multiple software tools with data transfers between them. Often lower-order methods or approximations are used as inputs.
This paper introduces a new workflow, where both conjugate heat transfer (CHT) and computational fluid dynamics (CFD) are calculated using a single Multiphysics tool. This turbine blade simulation method means air temperatures and blade temperatures are calculated simultaneously. The paper discusses the benefits of this workflow and shows validation of results obtained using it.
