Heat transfer efficiency will improve when fluid passes via pathway curvature pipes. It is generally known that heat transmission in a spiral coil is greater than in a straight pipe. The detailed characteristic of Heat transfer & flow of fluid is not shown in this report. This report brings out cfd analysis of how Improves transfer of heat & drop in pressure. With the help of this analysis, we will be able to predict Transferring heat & pressure drop inside a Spiral tube. CFD simulation is carried out for Spiral coils by varying coil parameters such as (i) diameter of tube (ii) Pitch of coil (iii) Number of Turns and their effects on heat transmission have been investigated. Since there is no Published Numerical, Analytical and Experimental details about spiral coils systems. In this report the laminar of flow pressure drop & Characteristics of transfer heat from spiral coil systems will be investigated with commercially available ANSYS FLUENT CFD package. The influences of parameters such as Newtonian fluid, Reynolds number, tube area or cross section, length to diameter ratio, coil pitch, number of turns on the Fluid flow as well as transfer of heat in spiral coils are investigated and presented. The CFD results are compared to previous researchers of experimental results, and they indicate good agreement.
