R & D Laboratories, DAIKIN INDUSTRIES,LTD. Sakai,Osaka,Japan This paper refers to an improvement of the lubrication in a rolling piston type rotary compressor. The lubrication conditions of lubricated surfaces are examined in running compressor and some parameters of them are numerically analyzed. It is elucidated from the investigation that,when unfavorable condition occurs,the metallic contac...

An enhanced version of the flexure-based microgap rheometer (FMR) is described which enables rheological measurements in steady state shearing flows of bulk fluid samples of PDMS with an absolute gap separation between the shearing surfaces of 100 nm – 100 μm. Alignment of the shearing surfaces to a parallelism better then 10 rad allows us to reliably measure shear stresses at shear rates up to...

In the field of tribology, many applications operate in elastohydrodynamic lubrication (EHL) regime e.g., automotive engines, gears and rolling element bearings. EHL hydrodynamic performances are significantly enhanced by contact bodies elastic deformations lubricant piezoviscosity. IssyOsborne is a procedure package for Igor Pro designed to be used researchers tribology fluid mechanics. It all...

Active matter is a term encompassing particle-based assemblies with some form of self-propulsion, including certain biological systems as well synthetic such artificial colloidal swimmers, all which can exhibit remarkable variety new kinds nonequilibrium phenomena. A wealth non-active condensed be described in terms collection particles coupled to periodic substrates, leading the emergence comm...
