A low Reynolds number (LRN) , k-e, turbulence model has been used to extend the validity of a standard k-e turbulence model deep into the viscous sublayer which is important for modeling mass transfer controlled corrosion in aqueous flow systems at high Schmidt numbers where the bulk of the resistance to mass transfer is embedded deep within the viscous sublayer.
The model has been applied to study of the local mass transfer and corrosion rates at a sudden pipe expansion, a sudden pipe constriction and a groove in a pipe.
