Calibration of a dynamic Eulerian-lagrangian model for the computation of wood cylinders transport in shallowwater flow 2019 Access copy available to the general public Unrestricted A computational Eulerian-Lagrangian model (ORSA2D_WT) is used for modelling the movement of floating rigid bodies on the water surface. The two-dimensional transport is computed with a dynamic approach, modifying existing formulations for the transport of bodies within fluid flows for the case of floating bodies, by adopting suitable added mass, drag and side coefficients. An original formulation for planar rotation is proposed, which includes the effect of the hydrodynamic torque and a resistance term, named added inertia, based on the difference between the angular velocity of the flow and that of the body. The value of the added inertia coefficient is calibrated against experiments made on purpose, involving the transport of a cylinder in a flume with two side obstacles. The calibrated code is applied to a slightly larger set of experiments for its preliminary evaluation. The outcome of the simulations shows that the streamwise and transversal displacements are well modelled, while some inaccuracies arise when considering the cylinder orientation. The effects of the initial conditions on the cylinders'' trajectory and rotation are discussed, showing their influence on the evolution of the rotation angles. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.728 2019 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS 71 / 109 = 0.651 2019 Q3 T2 WATER RESOURCES 60 / 94 = 0.638 2019 Q3 T2 ENVIRONMENTAL SCIENCES 182 / 265 = 0.687 2019 Q3 T3 ENGINEERING, CIVIL 72 / 134 = 0.537 2019 Q3 T2 0.616 2019 Civil and Structural Engineering 2019 Q2 Water Science and Technology 2019 Q2 Geotechnical Engineering and Engineering Geology 2019 Q2 Atmospheric Science 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Petaccia, G.
