A three-dimensional turbulent forced convective heat transfer and ﬂow characteristic, in a helical triangular cross sectioned coiled tube is simulated using the k–ɛ standard turbulence model and compared to results corresponding to circular cross sectioned helical tube. A finite element method is employed to solve the governing equations. The effects of Reynolds number, on Nusselt number, velocity and temperature profiles are discussed. The numerical computations show the developments and distributions of heat transfer and flow fields in the tube. These profiles are altered by the effect of curvature inducing the centrifugal forces.
