Sažetak
A new object oriented code named OpenFOAM, released by OpenCFD Ltd and aimed at solving continuum mechanics problems, has been provided with suitable tools for predicting ows involving heat transfer and combustion in conditions typical of turbomachinery applications. OpenFOAM supports operatorbased implicit and explicit second and fourth-order Finite Volume (FV) discretization in three dimensional space and on curved surfaces. Expansions have been added in this directions: Development of an All-Mach pressure based solver for co-located arrangement, development of RANS eddy viscosity isotropic and anisotropic models with particular interest of wall treatment, development of combustion models for premixed, partially premixed and diusion ames and development of radiative heat transfer models. Tests for validation here presented concern geometries for impingement as well as lm and internal duct cooling turbine blade. While for combustion and radiation typical testcases for the validation was simulated. All the simulations results were compared against in-house and from literature experimental data.
