AB  - Recently, it was important to improve heat transfer performance of heat exchanger because they were
considered general equipment. Heat exchangers have many applications such as power production units, home
appliances, manufacturing companies and transportations. The current study presents results obtained from
experimental investigations the enhancement the heat transfer by a horizontal tube through means changing
twisted tape that insert in pipe tube with water as a working fluid. The thermo hydraulic performance depends
on several factors such as configurations of geometry insert. An experimental and numerical investigation via.
ANSYS 11.0/ Flotran is carried out with twisted tapes under different shape configuration of tapes. Sixteen
cases are investigated in this study, firstly, the tube without holes in the tape is tested with different hole
diameters (4, 7.5 and 10.5 mm) each one has 1-4 twists. It can be concluded that the number of twisted tapes was
directly proportional to the velocity and inversely with temperature. The hole diameters in the twisted tape have
an effect on the distribution of temperature and velocity. Good agreement is evident between experimental and
numerical results with discrepancy 4%. It was found that the tape with two twists superior in heat transfer about
(31%) as compared with another twisted tapes.
