Analysis on mechanism of material removal rate and surface flow machining process [PDF]

open access: yesMATEC Web of Conferences
A novel finishing technique called abrasive flow machining (AFM) uses abrasive particles as the instrument for material removal. The term "self-deformable stone" refers to the abrasive particle-containing carrier medium, and AFM is commonly known as "no ...

Numerical Study of the Effect of Magnetic Field on Nanofluid Heat Transfer in Metal Foam Environment

open access: yesGeofluids, 2021
The magnetic field can act as a suitable control parameter for heat transfer and fluid flow. It can also be used to maximize thermodynamic efficiency in a variety of fields. Nanofluids and porous media are common methods to increase heat transfer.

Increasing exhaust temperature to enable after-treatment operation on a two-stage turbo-charged medium speed marine diesel engine [PDF]

open access: yes, 2018
Nitrogen-oxides (NOx) are becoming more and more regulated. In heavy duty, medium speed engines these emission limits are also being reduced steadily: Selective catalytic reduction is a proven technology which allows to reduce NOx emission with very high

The flow properties of foam [PDF]

open access: yes, 1988
The rheological behaviour of foam, prepared from an aqueous solution with lauryl sulphate as surfactant, has been measured with a viscometer as a function of the blow ratio, bubble diameter distribution and concentration of the thickener used.
