摘要：

The effects of torsion, aspect ratio and curvature on the flow in a helical pipe of rectangular cross- section are studied by introducing a non-orthogonal helical coordinate system. Spectral method is applied as main tool for numerical approach where Chebyshev polynomial is used. The numerical calculations are obtained by the iterative method. The calculations are carried out for 0 <= delta <= 0.02, 1 <= lambda <= 2.85, 1 <= gamma <= 2.4, at D-n = 50 & 100 respectively, where delta is the non-dimensional curvature, lambda the torsion parameter, gamma the aspect ratio and D-n the pressure driven parameter (Dean number)..
