Effects of inflow conditions on low mass-damping cylinder subjected to vortex-induced vibrations

Autor: Daniel Mella, Wernher Brevis, Luca Susmel

This work analyses the effects of the inflow conditions on the bifurcations characteristics of a two-degree-of-freedom low mass-damping cylinder undergoing vortex-induced vibrations. A two-dimensional RANS model was implemented to simulate the fluid�

Single cylinder subjected to vortex-induced vibrations: estimating cyclic stresses for fatigue assessment

Autor: Luca Susmel, Daniel Mella, Wernher Brevis

Publikováno v: Procedia Structural Integrity. 28:511-516

This study estimates the cyclic (i.e. fatigue) stresses on a pivoted cylinder subjected to a range of fully developed turbulent flows. The tested cylinder configuration allowed to transfer the complex fluid-structure interaction forces to a bottom-fi

Quantifying the Impact of Uncertainty within the Longitudinal Dispersion Coefficient on Concentration Dynamics and Regulatory Compliance in Rivers

Autor: Wernher Brevis, V. V. Camacho Suarez, Alma Schellart, James Shucksmith

Publikováno v: Water Resources Research. 55:4393-4409

The one‐dimensional advection dispersion equation (1D ADE) is commonly used in practice to simulate pollutant transport processes for assessment and improvement of water quality conditions in rivers. Various studies have shown that the longitudinal
