Computational Analysis of Air Lubrication System for Commercial Shipping and Impacts on Fuel Consumption [PDF]

open access: yesComputation, 2020
Our study presents the computational implementation of an air lubrication system on a commercial ship with 154,800 m3 Liquified Natural Gas capacity. The air lubrication reduces the skin friction between the ship’s wetted area and sea water.

Tribological behavior of aeronautical steel under oil–air lubrication containing extreme-pressure and anti-wear additives

open access: yesAdvances in Mechanical Engineering, 2016
If the lubrication system of a helicopter reducer is compromised, its gears and bearings will be in a working state without lubricating oil, which causes the reducer to be damaged in a very short time.

Experimental and numerical investigation of air lubrication on a planing hull with Double Interceptor System

open access: yesOcean Engineering
The present paper presents the study of the application of air lubrication system (ALS) on DIS (Double Interceptor System) equipped hull to improve its performances. It was observed that without ventilation, the low-pressure area behind the forward interceptor leads to excessive downforce, reducing trim and rise and increasing wetted surface with ...
