Optimization of the Corrugated Pipe for The Enhancement of the Heat Transfer

By using the Passive method for enhancing the heat transfer with minimum pressure drop change in the geometrical modification of internally pasted rib’s with length 15 mm and diameter of that fins are 1 mm that will help to disturb the laminar sub layer which is created in turbulent region in the boundary layer. By using modelling software CATIA V5, creating the smooth pipe model and models with different orientations of angle 00, 300, 450, 600, 900 in the direction of the fluid flow. These models imported in the software ANSYS version 15.0 with the extension. stp and created the fluid domains of different orientation of the pipes for fluid flow analysis. The Meshing of these fluid domains is required for fluid flow analysis for the CFD software. The accuracy of the meshing which is acceptable for the analysis is refers to Skewnees which is in the range of 0 to 1. The Computational Fluid Dynamics (CFD) with FLUENT as a solver used, the simulation of heat transfer and fluid flow analysis in the Laminar and turbulent region in tubes with internally rib’s are done. From analysis it found that 30 deg orientation pipe gives more heat transfer with minimum pressure drop as compared with other orientations of pipe. Over all 33.5 % increment is achieved with using internal ribs in pipe as compared to smooth pipe.
