A mathematical model based on orthogonal curvilinear coordinate system is developed which applies several algebraic stress models to simulate secondary currents in helically coiled channels. The model is validated using measurements in curved open channels with a simple rectangular cross-section. Se
## Abstract 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 numbe
