Abstract
– Heating and cooling are two important processes in thermal engineering and play a vital role in industries such as power plants, chemical process plants, manufacturing processes, automotive and electronics. Conventional heat transfer fluids like water, oil, and glycols have poor heat transport capabilities and they hardly meet the present-day requirements of high heat dissipation rates in compact heat exchangers. The aim of the present experimental work is to study the heat transfer characteristics of an antifreeze water- propylene glycol based CuO nanofluids flowing in a tube, under constant heat flux boundary conditions in laminar and transition flow regimes. The use of inserts with nanofluids to further compound the heat transfer enhancement is a new technique.
