This paper reports computational fluid dynamics analysis on the friction factor, Nusselt number and thermal-hydraulic performance of a tube equipped with the modified classic twisted tape inserts 1)Classic twisted tape with triangular holes 2) Classic twisted tape square holes 3) Classic twisted tape with nails. The results showed that the Nusselt number and performance of the modified classic twisted tape insert with nails were higher than other ones. A maximum increase of 12.5% and 10.6% were observed in the calculated Nusselt number and performance of the classic twisted tape insert with nails as compared with those obtained for the classic ones. The higher turbulence intensity of the fluid which is near to tube wall has been expressed as the main reason for observations.
