Flow and mass transfer characteristics for interacting side-by-side cylinders.

This study investigates the local and global flow structures and mass transfer characteristics for a group of interacting side-by-side cylinders in unbounded flow. Configurations with 2, 3, 4, and 5 members are considered for a range of pitch-ratios ( ) at the Reynolds number =90. The focus is laid on the time-averaged and instantaneous local flow features including wake field, jet flow, vortical structures, , pressure coefficient, and mass transfer coefficient as well as integral variables including hydrodynamic forces.
