Abstract
An experiment was designed to test the pool boiling performance of 3 nm gold nanofluid on a flat circular copper coupon. Compared to pure water, an increase of up to 175% in the critical heat flux was seen with gold nanofluids. However, a 25-30% deterioration in the heat transfer coefficient was also observed. The heating surface was observed before and after boiling with a scanning electron microscope. A thin, dark film was observed on the surface, which was due to the deposition of gold particles.
