Abstract
Study of flow resistance characteristics of curved tube are of prime importance as they are extensively used in coiled tube heat exchanger, hydraulic and pneumatic systems. From the literature review, it is found that for tubes with varying curvature, the flow resistance characteristics are not explored in much details. The present article presents the flow resistance characterises of conical spiral tube as well as the influence of geometrical and fluid flow parameters on local and global flow resistance using the numerical simulation approach. The simulation results reveal that the local distribution of pressure loss coefficient is mainly influenced by geometrical parameters such as (cone taper angle, coil pitch, curvature ratio). A correlation is proposed for the prediction of friction factor (fCS) in conical spiral tubes in turbulent regime.
