Abstract

Microstructured surfaces have been found to be energy efficient and cost effective through enhancement of heat transfer, drag reduction and anti-fouling in areas such as thermal engineering, fluid mechanics, microelectronics and transportation. However, their use with the condensation phenomenon has yet to receive considerable attention. Therefore, based on a new approach to recover energy in humid environments, the influence of different geometries manufactured on stainless steel inserts via micro-wire electro discharge machining (µ-WEDM) on condensation was analysed. The experimental work was carried out in a chamber with a high percentage of relative humidity (% RH) comparing the geometries against an unstructured surface. The experimental results showed a differential temperature (ΔT), 26% higher than the unstructured surface. Thus, it is reasonable to believe that this experimental study could be used in the design of energy recovery systems to enhance condensation heat transfer.
