Analysis of Laboratory Scale Premixed V-Flame Using RANS Simulation

This report presents a Reynolds-Averaged Navier-Stokes (RANS) simulation of a laboratory-scale turbulent rod-stabilized premixed V-flame, based on the experimental setup of Bell et al. The study investigates a stationary, non-planar flame oblique to the mean flow, focusing on mean shear, tangential convection, and flow divergence. The experimental results serve as a benchmark for comparing RANS calculations, with a particular emphasis on comparing several scalar dissipation models within the context of the BML approach. The numerical details, including the computational domain, boundary conditions, and grid resolution, are discussed. The report also covers the treatment of entrainment air and inlet conditions, the solution algorithm using Code_Saturne, and a detailed discussion of the results, including mean axial and transverse velocities at different locations downstream of the stabilizing rod.
