Notes:
Numerical solution of steady laminar flow in helically coiled tubes of square cross section for Dean numbers from 0.8 to 307.8 reveal two regimes of secondary flow. Up to Dean number of 100, the expected secondary flow pattern appears with twin counterrotating vortices. Above Dean numbers of 100, a new secondary flow regime, reported here for the first time, appears with four vortices. Flow visualization and pressure drop experiments confirm the transition.
