Abstract

It is now crucial for engineers to enhance procedures and boost heat exchanger efficiency. Heat exchanger performance can be significantly enhanced by a variety of methods. Composite-based fins or enlarged surfaces are frequently utilized to increase the air-side heat transfer rate in a variety of heat transfer applications. Because composite materials are lightweight, highly thermally conductive, and resistant to corrosion, they were used. A composite based fin’s efficiency is influenced by its fin geometry, material thermal conductivity, boundary condition at the fin tip, and heat transfer coefficient (h) at the fin surface. An aluminium test piece with thicknesses of composite-based fin for 0.5milimeter, 0.6 millimeter, and 0.7 millimeter with fin pitches of 4.23 millimeter and 6.35 millimeter was used to calculate heat transfer for forced convection. According to the results, a 4.23millimetre gap maximizes heat transfer, suggesting that more fins work better. Colburn’s factor (j) was computed for forced convection on an aluminium sample with composite-based fin pitch of 4.23 millimeter and 6.35 millimeter and helical fin thicknesses of 0.5milimeter, 0.6 millimeter, and 0.7 millimeter. According to the test results, composite -based fin pitch has very less influence on the Colburn factor (j). An aluminium test specimen with helical thicknesses of composite-based fins like 0.5milimeter, 0.6 millimeter, and 0.7 millimeter with composite-based fin pitches of 4.23 millimeter and 6.35 millimeter have been used to compute friction coefficient for forced convection. According to the findings, using composite materials in heat exchanger design can result in notable increases in energy savings and heat transfer efficiency.

Keywords: Composite material, Spiral fin tube heat exchanger, friction factor, fin thickness, heat transfer performance.
