The solidification processes of titanium (TiO2) nanofluids and deionized water (DW) were measured by differential scanning calorimetry to explore the effect of sodium dodecylsulfate (SDS) surfactants on the supercooling degree of TiO2 nanofluids. The supercooling degrees of TiO2 nanofluids...

One or more interconnected steam power plants (SPPs) are constructed in a petrochemical complex to supply utility energy to the process. To avoid large economic penalties or process shutdowns, these SPPs should be flexible and reliable enough to meet the process energy requirement under varying...

Two titania–water (TiO2–water) nanofluids were prepared by dispersing TiO2 nanoparticles in rod shapes (rutile TiO2) and in spherical shapes (anatase TiO2) into deionized water. The effect of the TiO2 nanoparticles on the crystallization behaviors of the nanofluids were investigated using...

Graphene is widely utilized because of its exceptional properties, such as strong mechanical strength, low weight, nearly optical transparency, and excellent conductivity of heat and electricity. In this study, we used the ultrahigh specific surface area of graphene due to its inherently...

The sustainable design configuration of utility systems incorporating pollutant emission abatement technologies has an important influence on economic cost, pollutant emission, and energy consumption of the process industry. In this paper, four typical cogeneration systems that address different...

This study evaluates the thermal hydraulic performance of a novel liquid–vapor separation condenser (LSC). A series of experiments was performed to investigate the in-tube heat transfer coefficient and pressure drop of the LSC with varying average refrigerant quality at constant mass flux. The...
