LES-based vortical flow characterization in a 90°-turned pipe bend

The present work is concerned with the characterization of the vortical flow topology within a 90°-pipe bend by means of a well-resolved, highly comprehensive Large-Eddy Simulation (LES). The considered flow configuration is closely related to the cooling channels encountered in the internal combust...
