Finite element analysis of turbulence models for confined swirling flows using LDV-measurements for verification J. Goerres, A. Fingerle, H.-C. Magel, U. Schnell Institut fur Verfahrenstechnik und ABSTRACT Measurements and computations of a highly swirling flow are presented. The isothermal flow expands into a highly confined test channel which represents the geometry of typical industrial furnaces. With the technique of Laser Doppler Velocimetry (LDV), measurements of mean and fluctuation velocities were made at several positions in the test channel. These data are used for a detailed evaluation of various turbulence models: the usually used standard k-e-model and two higher-order turbulence models, the Algebraic Stress Model (ASM) and the Effective Viscosity Hypothesis (EVH). These models are incorporated into a finite element program. In addition to the LDV-measurements, the finite element results are compared to predictions obtained with a finite volume code.
