Original Abstract

This paper utilizes current state of art in CFD simulations suitable for engineering application. The object of interest is an axial guide vane swirl generator often found in process burners. The aim is to validate available turbulence models suitable for flow field prediction in industrial combustors. The grid independence study on four grids supports choice of used grid. Influence of the outlet shape on the flow field inside the chamber and especially on recirculation zone shape is proved. Last, the comparison of the three turbulence models is provided. The most accurate is identified the Reynolds Stress turbulence model. Predicted velocity fields are compared with the measured data obtained from the literature. CFD predictions of all the turbulence models underestimate peak axial velocity and overestimate velocity in central recirculation zone on the chamber axis.
