Pore scale study of crude oil distribution and interfacial processes in unconsolidated porous media: an application of synchrotron x-ray microtomography
… model reservoir systems most amenable to oil recovery by investigating the behavior of three fractions of crude oil distribution and morphology in three types of porous media with increasing heterogeneity (in grain size distribution) during sequential surfactant flooding episodes. Multiple …

An experimental study of the oil evolution in critical piston ring pack regions and the effects of piston and ring designs in an internal combustion engine utilizing two-dimensional laser induced fluorescence and the impact on maritime economics
Faced with increasing concern for lubricating, oil consumption and engine friction, it is critical to understand the oil transport mechanisms in the power cylinder system. Lubricating oil travels through distinct regions along the piston ring pack before being consumed in the combustion chamber, …

Transient distribution of refrigerant and oil in a residential heat pump water heater system
In most vapor-compression refrigeration systems, oil is added into the compressor for lubrication. However, it is inevitable that a portion of oil escapes from the compressor and circulates throughout the system due to the mutual solubility between the refrigerant and oil. The presence of …

Characterization of oil transport in the power cylinder of internal combustion engines during steady state and transient operation
Engine friction, wear, and oil consumption are some of the primary interests for the automotive industry. However, there is currently a lack of understanding of the fundamentals involving oil transport inside the power cylinder. Therefore, improving one area of engine performance, such as friction, …

Curved beam based model for piston-ring designs in internal combustion engines
… ring behavior is inherently associated with the oil consumption, friction, wear and blow-by in internal combustion engines. This behavior varies along the ring's circumference and determining these variations is of utmost importance for developing ring-packs achieving desired performances in …
