This paper follows the propagation of pollution in a river with rectangular cross-section bed and variable cross-sectional velocity. The calculations were made for steady flows pollutant concentrations. To approximate velocity distribution set equations current vorticity functions was solved. concentrations calculated from bidirectional advection turbulent diffusion equation. Analysis leads to ...

Dry and lubricated highly deformed contacts appear in engineering, physics, bio-(fluid)mechanics, with increasingly many applications where the soft materials can exhibit viscoelastic behaviour. In this work, solid point contact problem has been studied theoretically experimentally. An efficient visco-elastohydrodynamic lubrication (VEHL) numerical algorithm developed by implementing a novel de...
