Hybrid Nanofluids for Low Temperature in Plate Heat Exchanger

This book is about the use of nanoparticles as nano-coating and as mono/ hybrid nanofluids in the plate heat exchangers. The plate heat exchangers are extensively utilized in many engineering applications because of their high thermal efficiency, compactness, flexibility and ease of sanitation. Their performance can be enhanced by using some advanced fluids instead of conventional fluids. Hybrid nanofluid is one of such pioneering heat transfer fluids, engineered by dispersing the mixture of nanoparticles (include metal oxides, metals and several allotropes of carbon) or nanocomposites in the conventional fluid. This manuscript presents the theoretical, experimental and numerical investigations on heat transfer and pressure drop characteristics of hybrid nanofluids as cold/hot fluid in the plate heat exchanger. Two different case studies have been performed with various brines based hybrid nanofluids in the plate heat exchangers for low temperature sectors. Hybrid nanofluid has been treated as a secondary refrigerant for plate evaporator in the first case and as a coolant for plate chiller in the second case. Energy, exergy and economic analyses have been performed.
