Abstract

A practical approach for BEM solution of heat conduction in large-scale three-dimensional film-cooled turbine vanes models E. Divo, A.J. Kassab & F. Rodriguez Mechanical, Materials and Aerospace Engineering Department, University of Central Florida Orlando, Florida, USA Abstract An iterative domain decomposition method is developed to solve 3-D BEM problems. The method is suited for parallel computation. 1 Introduction The motivation behind this work lies in conjugate heat transfer modeling of turbomachinery components using the temperature-forward flux-back (TFFB) loosely coupled boundary element-finite volume method developed by the authors[l]. As it is well known, the boundary element method (BEM) only requires a surface mesh to solve heat conduction problems. However, once boundary conditions are imposed and the final algebraic system assembled, the resulting matrix is fully-populated. For large-scale problems, this poses serious challenges due storage requirements and iterative solution
