The effect of torsion on convective heat transfer in a curved annular sector duct with a finite pitch has been numerically studied. Seven parameters have been identified as major variables describing the flow pattern. The results indicate that torsion will rotate the temperature contours to one side and distort their symmetry. Increasing the Prandtl number will significantly enhance the effect of torsion on the temperature distribution. The torsion effect may also be considerably enhanced by increasing the curvature, the axial pressure gradient, and with a decrease of the radius ratio. Furthermore, the predicted results have been compared with the experimental data, and excellent agreement is achieved.
