Characteristics of free and impingement spray fueled with methanol, ethanol, isooctane, toluene reference fuels (TRF) and gasoline were investigated by using a Phase Doppler Anemometry (PDA) system with a direct injection gasoline injector. Results show that all these fuels performed a similar impingement process: a large fraction of incoming droplets adhered to the wall because of the stick and spread...
Understanding and controlling the gas flow at the nanoscale has tremendous implications in the fields of separation science, catalytic reactions, and energy storage, conversion and extraction. However, the gas flow behavior at the nanoscale is significantly different from that occurring at larger scales. In this work, we focus on a real gas effect, stemming from a strong gas intermolecular interaction...
The KI-impregnated activated carbon (KI-AC) was synthesized to investigate its capacity for elemental mercury (Hg0) removal under the simulated flue gas. The Hg0 removal performance is significantly promoted by KI loading. The effect of reaction temperature and activated carbon porosity on Hg0 removal, and calculation on desorption activation energy of adsorbed mercury species were employed to identify...
In the present study, the polycyclic aromatic hydrocarbons (PAHs) and soot particulates emitted from a gasoline direct injection (GDI) engine were sampled and analyzed. The results show that the vapor-phase PAHs and particulate-bound PAHs exist in GDI engine exhaust emissions. Soot particles are formed by the agglomeration of the quasi-spherical primary carbon particles, and the size of the PAH cluster...
In gas condensate reservoir, liquid condensation near the wellbore region might kill gas well deliverability, research shows that gas-wetting alteration can be one of effective methods to alleviate liquid condensation in porous media. However, the wettability of cores can only be altered from liquid-wetting to intermediate gas-wetting, making the improvement for gas well deliverability very limited...
