Abstract/Summary Different heat transfer surface extension techniques are considered in order to improve the performance of an air-cooled heat exchanger and an optimisation process on a Solar Enhanced Natural Draft Dry Cooling Tower (SENDDCT) is conducted by Queensland Geothermal Energy Centre of Excellence (QGECE), as the air-cooled condenser of a geothermal power plant. The conventional method of extending the heat transfer area by means of fins is compared with a modern technique being the application of a thin metal foam layer to the outer surface of the tube. Aiming at maximizing the heat transfer enhancement and minimizing the total pressure drop, different tube bundle arrangements are numerical investigated by ANSYS-Fluent where the number of rows and tube spacing are systematically changed. An optimum design ispresented for an existing tower to be equipped with solar panels to afterheat the air leaving the heat exchanger bundles arranged vertically around the tower skirt.
