## Abstract Laminar flow in helically coiled tubes is treated numerically. Fully developed axial and secondary velocities are calculated for both circular and elliptical cross sections. Only closely wrapped helices, that is, helices with modest pitch, are considered. Ten solutions with Deans number
## 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
## Abstract The numerical method of Part I is extended to study periodic laminar flow in helically coiled tubes of square cross section oscillating sinusoidally about their helix axis. Depending on the relative strength of the wall velocity and the velocity of flow through the tube, one of three fl
