Abstract—This paper presents the application of CFD for parametric investigations in the design of combustor. A can type combustor with non-swirling and swirling flows at inlet is considered for the analysis under isothermal environment. The flow characteristic in the annulus region of combustor model is looked into. The commercially available code ‘FLUENT’, based on finite volume technique and incorporates the standard k- turbulence model has been used to carry out the predictions. The numerical results are validated against experimental results and a reasonable matching is observed.
