Summary This paper presents the comparative experimental and numerical study of heat exchange through tapers helical and spiral tube. The efficiency of heat exchange is increase the thermal performance as well as productivity. The main study was a focus on these two shapes of pipe at various process parameters like mass flow rate and inlet temperature conditions. Co‐relation equations were developed for both shapes of pipe with a linear fitting tool available in MATLAB coding software. Proper instrumentation and calibration were taken care in this work. The simple horizontal pipe was used to validate the experimental results with computational fluid dynamics (CFD) results. Experimental validation proves that CFD is an effective tool for thermal performance investigation. The main conclusion of present work was that spiral tube displays enhanced thermal enhancement than the helical tube for all process conditions. Thermal contours are also developed for more detailed study on both shapes of the tube.
