Simplified theory of the Archimedian screws [PDF]
Journal of Hydraulic Research, 2009 The Archimedean screw pump is one of the oldest hydraulic machines. Today, it is employed in pumping as well as - operating in reverse - in an energy conversion role. Despite its age, no consistent theory links the screw’s geometry with its mechanical efficiency. Based on geometrical parameters and an idealised energy conversion process for one turn of

Dynamic Interaction of a Heavy Crane and a Ship in Wave Motion [PDF]
Modeling, Identification and Control, 2018 Previous work on the dynamics of vehicle-manipulator systems is extended to offshore ships with heavy cranes. The proposed method is based on a Newton-Euler formulation where the forces of constraint are eliminated using projection matrices based on the ...

Numerical analysis of the hydrodynamic behaviour of immiscible metallic alloys in twin-screw rheomixing process [PDF]
, 2006 A numerical analysis by a VOF method is presented for studying the hydrodynamic mechanisms of the rheomixing process by a twin-screw extruder (TSE). The simplified flow field is established based on a systematic analysis of flow features of immiscible ...

Parametric analysis and design of straight screw extruder for solids compaction
Journal of King Saud University: Engineering Sciences, 2019 Screw extruders are commonly used in the food and polymer industries. Scientifically designed screw extruders for biomass compaction equipment are required to limit the existing problems faced in the industry. In this study, models based on the plug flow

A Mathematical Modeling and Analysis Method for the Kinematics of a Maglev Train
Machines, 2022 In recent years, more and more countries are paying attention to maglev transportation because of its outstanding advantages. However, because the structure of a maglev train is more complex than a wheel-rail train, there is no systematic theory method ...

Vision-Based Hybrid Controller to Release a 4-DOF Parallel Robot from a Type II Singularity
Sensors, 2021 The high accuracy and dynamic performance of parallel robots (PRs) make them suitable to ensure safe operation in human–robot interaction. However, these advantages come at the expense of a reduced workspace and the possible appearance of type II ...
