THE EFFECT OF SWIRLING NUMBER VARIATION ON TURBULENT TRANSPORT AND MIXING PROCESSES IN SWIRLING RECIRCULATING FLOWS: EXPERIMENTAL AND NUMERICAL INVESTIGATIONS
SINOPSIS
In this work, confined swirling reactive as well as non-reactive recirculating flows are analyzed experimentally and numerically. Extensive turbulent flow field measurements for the determination of the velocity components and the Reynolds stresses using 2D-Laser-Doppler Velocimetry are presented. In addition, selected results of Raman measurements for the simultaneous determination of temperature, mixture fraction and major species concentrations performed by Meier et al. (2000) at an identical setup are included for a complete comparisation of scalar as well as flow fields to numerical calculations based on RANS-modelling approach. Such results can be used to improve the understanding of the effects of swirl number variation on relevant transport and mixing processes and to provide an outstanding data base for subsequent development and validation of turbulence, mixing and turbulence-chemistry interaction models.
