Spiral tubes are widely used in various engineering applications like heat transfer among various fluids, refrigeration applications and many more. The optimum spiral tube can improve efficiency of the system. So various research is carried out on spiral tubes design and process parameters in previous decades. In present paper effect of friction factor is studied for spiral tube by chaining its process and design parameters. The present study is based on CFD simulation technique. Experiments are designed using “Taguchi Method”. The three process parameters which are identified for this study is wall temperature of surface, fluid inlet temperature and mass flow rate of fluid. Three design parameter which are selected for this study are inner diameter of tube, pitch of tube and curvature ratio of tube. Total six parameters are selected and then experiment table is generated using Taguchi method and 36 experiments are generated which are then simulated using Ansys Fluent (Version 14.5) software. Experiment validation is performed using previous experiment work on spiral tube. Friction factor is response parameter selected for this study and the analysis is performed using Signal to noise ratio parameter. To improve the effect of pressure-drop or decrease the friction factor in spiral tube the most reliable parameter is inner diameter of tube and least parameter is wall temperature of tube. Pitch is another important parameter for friction factor analysis.
