Numerical modelling of the effect of appendages on turbulent mixing in connected nuclear fuel subchannels
Abstract
The effects of appendages on flow characteristics and scalar mixing in gap-connected twin-subchannel geometries has been investigated. Mixing is assessed for a symmetric, rectangular compound channel geometry connected by a single rectangular gap using computational fluid dynamics (CFD). Detailed numerical models, characterizing the full test section from a reference experimental study, are generated and validated against measurements. Time …
