OpenFOAM TURBO TOOLS: FROM GENERAL PURPOSE CFD TO TURBOMACHINERY SIMULATIONS
OpenFOAM is an established object-oriented li- brary for Computational Continuum Mechanics, with emphasis on CFD. It implements physical models of fluid flow, structural analysis, heat and mass transfer using equation mimicking, with un- structured polyhedral mesh support and massive parallelism in domain decomposition mode. In order to use OpenFOAM in turbomachinery CFD, its “general purpose” capabilities are en- hanced with turbo-specific features, related to physics of rotating regions and rotor-stator in- terfaces. Handling for geometric simplifications of multi-blade and multi-stage rotating machines are implemented, including simple stage inter- faces, non-equal pitch of blade passages, pitch-wise cyclicity and mixing plane averaging. In this paper we describe the implementation of turbomachinery-specific features in OpenFOAM, in the spirit of object orientation and C++. Empha- sis is given to the basic functionality of turbo tools, software layout in OpenFOAM, numerical formu- lation of stage interfaces and their place in overall code design. The paper is concluded with examples of turboma- chinery simulations, illustrating the capability of turbo tools on industrial cases of incompressible and compressible turbomachinery flows.
