N2 - The double pipe heat exchanger is one of heat exchanger type which has one pipe placed concentrically inside the pipe which has a larger diameter. There are two fluids flow through double pipe heat exchanger. One fluid flow in the inner pipe, and the other fluid flow in annulus with different temperature. The performance of a double pipe heat exchanger is based on heat transfer coefficient, pressure drop, and effectiveness. Heat transfer coefficient and pressure drop are characterized by Nusselt number and friction factor. A way to increase the performance of double pipe heat exchanger is by a passive method with adding twisted tape in the inner pipe. This research has been done by experimental and numerical study with additional perforated twisted tape which has a 3.77% porosity ratio. The testing was done with a range of Reynold number in an inner pipe is 1000-5000 and with an inlet temperature of the water is 50°C. In addition, Reynold number in the annulus is 20000 with an inlet temperature of the water is 20°C. The results show that using of perforated twisted tape with porosity ratio 3.77% is showing better performance than plain twisted tape. Porosity ratio of 3.77% could be increase the Nusselt number with average value on a plain tube by 0.31% and increase the average friction factor on a plain-tube by 366.34%. Furthermore, double pipe heat exchanger rise the average of NTU on a plain tube by 78.42% and also increasing the average value of ϵ on a plain tube by 45.86%.
