Elastohydrodynamic Lubrication

Dear Colleagues,

It has been nearly 80 years since the first research work was published on elastohydrodynamic lubrication (EHL). Thereafter, extensive research work has broadened our EHL knowledge utilising both numerical modelling methods and advancing experimental techniques. EHL is a lubrication regime generally happens between non-conformal surfaces, in which applied load on a small contact area results in very high local pressure typically ranging from 1 to 3 GPa. This high contact pressure leads to an increase in lubricant viscosity and elastic deformation of surfaces. Such phenomenon can be widely observed in lubricated machine components, such as rolling bearing, gears, cams and tappets, vane pumps, etc. It, therefore, requires better understanding of EHL to optimize lubricant formulation, increase machine efficiency and durability, and improve machine performance.

This Special Issue welcomes researchers to present their recent progress and insights into the field of EHL and deliver guidance to both academia and industries. Research areas include, but are not limited to, EHL traction, film thickness, contact mechanics, surface engineering, machine efficiency, rheology, and mechanochemistry.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Machines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
