Abstract: The drag force law acting on a moving circular disk in a two-dimensional granular medium is analyzed based on the discrete element method (DEM). It is remarkable that the drag force on the moving disk in moderate dense and ...

Abstract: A series of experiments was carried out to investigate transient axial thrust caused by pump starting. Conditions of discharge piping pressure distribution around the impellers and the relation ...

Abstract: In Japan, the Public Works Research Institute of the Ministry of Construction has started the development of a road‐automobile communication system (RACS) under a joint research program with 25 private companies. The subject ...

Abstract: The present paper deals with an analysis of the kinematics and geometry of the tooth engagement of the harmonic drive, and presents a new method for determining tooth profiles of the harmonic ...

Abstract: This paper presents a three-dimensional quasi-static analysis of continuous or jointed pipelines. Transfer Matrix Method was applied to the analysis providing for nonlinear behaviors of joints and ...

Abstract: The sealing effects of squeeze air film were analyzed experimentally and theoretically. The air flow rate and the sealed pressure were measured in a squeeze face seal. The air flow rate can ...

Abstract: The dynamic pressure in a squeeze film and the air flow through the film were analyzed experimentally and theoretically. The dynamic pressure was measured in a squeeze film between two rectangular ...

Abstract: The high temperature isolation valve (HTIV) is a key component to assure the safety of a high temperature gas cooled reactor connected with a hydrogen production system for protections of ...
