The turbulators have been studied as a device of the heat transfer enhancement in a tube. This paper presents the results of the heat transfer and the pressure drop in a round tube using a wire coil as the turbulator. The wire coil inserts are relatively low in cost and are easy to exchange. This paper is shown the experimental results, positional effects on the heat transfer and the pressure drop in a round tube, in the case that the diameters of the wire coils were made smaller than the inside diameter of the tube.
