Abstract
This study aims to design and assess a shell and coiled tube heat exchanger that uses gold nanoparticles dispersed in a heated up base fluid. The theory about nanofluids, as well as the procedure to design and test a functional prototype of this heat exchanger are presented. 3D drawings showing the main dimensions of the device and other construction details are also included. Preliminary experimental tests at several operating conditions were carried out to verify the effect of the nanofluid in improving the heat exchanger efficiency. Results obtained from preliminary tests of the proposed coil heat exchanger, operating with distilled water and the nanofluid, show an increase in the overall heat transfer coefficient when the gold nanoparticles are used in the heated stream. This work provides an extra tool for the study on the unique characteristics of heat transfer using nanofluids.
