Thermal characteristics of helical coiled heat exchanger with graphene-deionized water on waste heat recovery of combustion stack gas
Overall heat transfer coefficient of helical coiled heat exchanger with graphene- deionized water (DI-water) for waste heat recovery of combustion stack gas including heat exchanger effectiveness, ε, were experimentally carried out. Various sizes of tube diameter (1.2-1.5 cm), coil diameter (19-24.5 cm), and coil pitch (2.8-6 cm) of helical coils 1-4 including different heat transfer…
