Resumo

This paper model sloshing in 2D tuned liquid column damper (TLCD) using a pressure based Eulerian
approach. The fluid domain is discretised by isoparametric quadrilateral 4-nodes (Q4) finite elements coded in
MatLab. A TLCD was modelled with rigid contours and a free surface to study uncoupled liquid reservoir. It is
performed free and forced (harmonic) analysis to determine dynamic parameters. The numerical results were
validated using experimental Alkmin’s results presenting acceptable errors (inferior of 1.7% relative error) with
less than 5k elements. The present numerical implementation presents a good agreement with analytical solution
and experimental results.
