Abstract
A relatively new class of coolants created by suspending 1-100 nm sized particles in a base fluid, have been shown to improve a fluid’s thermal properties. My research focuses on two methods using nano fluids to deposit nanoparticles for the creation of enhanced surfaces for boiling heat transfer. Since many of these thermal management systems require a nonconductive fluid, the electrical conductivity of nano fluids is also studied. Pool boiling studies of nanofluids have demonstrated either enhanced or diminished boiling heat transfer, yet have been unable to distinguish the contributions of increased surface roughness and suppression of bubble transport by suspended particles. This uncertainty is resolved by studying the boiling performance of a surface exposed to a series of boiling tests that alternate between water and a water-based nano fluid. The boiling performance of the coated surfaces increases significantly with each cycle. The measured surface roughness of the intervening nanoparticle layers is used with a model to explain the measured increase in performance. The results demonstrate that the effect of increased surface roughness due to nanoparticle layering can enhance boiling for the base fluid. “A novel method to create enhanced boiling surfaces is electrophoretic deposition of nanoparticles from a nano fluid. A surface was coated using electrophoretic deposition from a ZnO-propylene glycol based nano fluid. With adequate coating time, such a surface modification method can increase the boiling heat transfer coefficient by about 200%, which was correlated to an increase in the nucleation site density.”
