by
Theoretical and experimental studies on waste heat recovery of combustion stack gas and heat transfer phenomena of a fully developed laminar flow of deionized water in vertical helical coils were carried out with coil dimensions: tube diameter to coil diameter, di/D=0.04-0.06 and pitch to coil diameter, p/D=0.1-0.25. The calculation of heat transfer data was based…

Heat transfer phenomena of a fully developed laminar flow of deionized water-based graphene nanofluids (DI-water/GNPs) in vertical helical coils for heat recovery of combustion stack gas was carried out with different helical coil dimensions. The GNPs particle concentrations were 0.05 and 0.08% by weight and the calculation of experimental heat transfer data was based on…

by
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…
