Abstract: Heat exchanger performance can be basically evolved by many heat transfer enhancement techniques. The current experimental and numerical investigations disclose the use of different twisted tapes inserted in a single tube heat exchanger for better fluid mixing which produces a higher rate of heat transfer comparing to that of smooth tube. The tube is made of from copper material of 2.3 cm inner diameter and 100 cm length. The experimental work is conducted in an insulated horizontal circular tube in the laminar flow region to test the influence of tap-inserts on the heat transfer enhancement and pressure drop, under constant heat flux condition. Two configurations of twisted tapes that are also fabricated from copper material with different Twist Ratios (TR = 4 and 6) are used. The numerical study is performed using the ANSYS Fluent 15.0 based on the finite volume technique for solving the governing equations, for different values of Reynolds number with water being as a working fluid.
