The pitcher plant has evolved its hierarchically grooved peristome to enhance a water-based slippery system for capturing insects with oil-covered footpads. Based on this, we proposed a hierarchically porous oil scoop (HPOS) with capillary-induced oil peel-off ability for repeatable spilled oil recovery.

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021
The under-race lubrication system providing a moderate amount of oil to high-speed bearings is one of the key factors to ensure its good lubrication and cooling. To investigate the oil capture performance of the oil scoop, a complete numerical calculation model was established, and unsteady simulations of oil–gas two-phase flow inside the under-race ...

Abstract Due to the continuous reduction of engine sizes, efficient under-race lubrication becomes ever more crucial in order to provide sufficient amount of oil to various engine components. An oil scoop is a rotating component that captures oil from a jet, and axially redirects it to the bearing, providing under-race lubrication. Given

A scoop net equipped with an underwater anti-oil-fouling (AOF) filter was tested for the cleanup of low-sulfur fuel (LSF). An underwater AOF filter [fabric/oxidized carbon soot (O-CS)/polyvinyl alcohol-Konjac glucommannan (PVA-KGM)] possessing a partially dissoluble surface was prepared by the stepwise coating of O-CS and PVA/KGM onto different fabrics.

Simulation and Analysis of Oil Scoop Capture Efficiency
Volume 1: Aircraft Engine; Fans and Blowers; Marine, 2018Under-race lubrication is the main method for the main shaft bearing of aero-engine which with higher performance. Oil scoop is an important part of the under-race lubrication structure, which plays an important role in capturing oil coming out of a stationary jet nozzle, and the efficiency of oil capture has great influence on the performance of the ...

Oil Scoop Simulation and Analysis Using CFD and SPH
Volume 7B: Structures and Dynamics, 2016The process of rotating scoops capturing oil coming out of a stationary jet nozzle was simulated with CFD (Computational Fluid Dynamics) and SPH (Smoothed Particles Hydrodynamics). The aim was to determine the efficiency of the oil capture, and the effects of varying parameters such as angular velocity of the scoops, the speed and direction of the oil ...

Prediction of Gas Turbine Oil Scoop Capture Efficiency
ASME 2014 Gas Turbine India Conference, 2014The lubrication system in a gas turbine engine is akin to the human blood circulatory system. Providing right quantities of oil to the right components for cooling and lubrication is the primary function of the lubrication system. In the current analysis, at the downstream end of the lube oil supply line, a stationary oil nozzle sprays a jet of oil to ...
