Abstract

The interest in increasing heat transfer is growing in line with industrial development. In relation to the cooling and heating systems, in particular in industrial-type boilers, the heating boilers and heat exchangers, the use of inserts to enhance heat transfer is quite common. During the design of the heat exchanger while increasing heat transfer, the friction hence the pressure loss will increase as well. As a matter of course, the cost of increased energy consumption for pumping fluid in tubes should be compensated with the reduction in cost of the device.

In this experimental study, turbulence creating flaps have been placed into the tubes and compared to the empty tube. Experiments have been carried out using three springs and three twisted tapes having different pitches, and five different Reynolds numbers. The effects on the friction factor and on the number of Nusselt were investigated.
