Control of backward-facing step flow using burst modulation with a DBD plasma actuator

Nihon Kikai Gakkai ronbunshu, 2016
In this paper, an experimental study is performed for channel flow over a backward-facing step, with a dielectric barrier discharge (DBD) plasma actuator (PA) as a flow control device that introduces periodic disturbance to the system.

Preventive measures of fretting wear in contact surfaces of inner ring and backing ring of railway axle journal bearings (Combined effect of grooving and segment‐structured DLC coating towards backing rings)

Nihon Kikai Gakkai ronbunshu, 2019
Fretting wear is surface damage caused by repeated slight relative slips between two contact surfaces. In railway applications, fretting wear may occur between the inner ring and the backing ring of an axle journal tapered roller bearing.

Empirical modeling of the quiet time nightside magnetosphere [PDF]

, 1994
Empirical modeling of plasma pressure and magnetic field for the quiet time nightside magnetosphere is investigated. Two models are constructed for this study. One model, referred to here as T89R, is basically the magnetic field model of Tsyganenko (1989)

On the Energy Required to Eject Processed Matter from Galaxies [PDF]

, 2001
We evaluate the minimum energy input rate that starbursts require for expelling their newly processed matter from their host galaxies. Special attention is given to the pressure caused by the environment in which a galaxy is situated, as well as to the ...
