Computation of recirculating swirling flow with the GLM Reynolds stress closure

Computation of recirculating swirling flow with the GLM Reynolds stress closure A Reynolds stress closure based on the generalized Langevin model (GLM), developed by Haworth and Pope[3,4], is applied to the flow calculation with swirl-induced recirculation. The purpose of the work is to assess the performance of this model under the complex flow conditions caused by the presence of strong swirl which gives rise to both unconventional recirculation in the vicinity of the symmetry axis and strong anisotropy in the turbulence field. Comparison of the computational results are made both with the experimental data of Roback and Johnson[11] and the computational results obtained with the typical isotropization of production model (IPM) and thek-ε type Boussinesq viscosity model. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Mechanica Sinica Springer Journals

Abstract

A Reynolds stress closure based on the generalized Langevin model (GLM), developed by Haworth and Pope[3,4], is applied to the flow calculation with swirl-induced recirculation. The purpose of the work is to assess the performance of this model under the complex flow conditions caused by the presence of strong swirl which gives rise to both unconventional recirculation in the vicinity of the symmetry axis and strong anisotropy in the turbulence field. Comparison of the computational results are made both with the experimental data of Roback and Johnson[11] and the computational results obtained with the typical isotropization of production model (IPM) and thek-ε type Boussinesq viscosity model.
