摘要：

A solution algorithm for the numerical calculation of isothermal fluid flow inside gas turbine combustors is presented. The finite-volume method together with curvilinear non-orthogonal coordinates and a non-staggered grid arrangement is employed. Cartesian velocity components are chosen as dependent variables in the momentum equations. The turbulent flow inside the combustor is modelled by the k-epsilon turbulence model. The grid is generated by solving elliptic equations. This solution algorithm, which can be used on both can-type and annular combustors, is tested on a water model can-type combustor because of the availability of geometrical and experimental data for comparison.
