Turbulent separated bluff-body flows are encountered in many industrial applications, such as external aerodynamics and gas turbine combustors. This type of flow is associated with separation of the boundary layers, vortex shedding and bluff-body stabilized combustion and has long been of interest to scientists and engineers. The goal of the study on which this AC is based has been to replicate experiments carried out in a test rig at Volvo [1,2,3]. Due to the simple geometry, this test case is quite attractive for verifying and validating new algorithms and models in the frame of computational fluid dynamics (hereafter CFD). The knowledge obtained can be applied to assess the predictive capabilities of the state-of-the-art CFD codes to model and simulate unsteady combustion physics.

Introduction
Turbulent separated bluff-body flows are encountered in many industrial applications, such as external aerodynamics and gas turbine combustors. This type of flow is associated with separation of the boundary layers, vortex shedding and bluff-body stabilized combustion and has long been of interest to scientists and engineers. The goal of the study on which this AC is based has been to replicate experiments carried out in a test rig at Volvo [1,2,3]. Due to the simple geometry, this test case is quite attractive for verifying and validating new algorithms and models in the frame of computational fluid dynamics (hereafter CFD). The knowledge obtained can be applied to assess the predictive capabilities of the state-of-the-art CFD codes to model and simulate unsteady combustion physics. The numerical results reported here are based on the work published in [4].
