ABSTRACT The most important aspect of the ongoing research project is to develop numerical coupled hydraulic-structural analysis models of oil containment booms. This should be later applicable for investigation of the efficiency limits of a new system of oil spill containment booms called Cavalli system. This system consists of surrounding the oil slick with a special boom and protecting it against waves and currents. It provides the possibility to divide the encircled area in several smaller circles and to increase the thickness of the oil slick inside. The whole system consists of a two-phase fluid (oil and water) and a boom that should be structurally stable for the pressure loads imposed by the fluids. It is finally important to evaluate the behaviour of the flexible skirt under different wave and current conditions, as almost all of existing research in the field have been undertaken for rigid barriers. To assess the behaviour of a flexible barrier fluid-structure interaction analysis is to be conducted. The problem is considered as a fluid-structure interaction problem as the boom usually undergoes large deformations and rotations, which modifies the flow characteristics during operation that is not the case for a rigid boom.

A numerical simulation has been conducted to investigate flow erosion and pipe deformation of elbow in gas-solid two-phase flow. The motion of the continuous fluid phase is captured based on calculating three-dimensional Reynolds-averaged-Navier-Stokes (RANS) equations, while the kinematics and trajectory of the discrete particles are evaluated by discrete phase model (DPM), and a fluid-structure interaction (FSI) computational model is adopted to calculate the pipe deformation. The effects of inlet velocity, pipe diameter, and the ratio of curvature and diameter on flow feature, erosion rate, and deformation of elbow are analyzed based on a series of numerical simulations. The numerical results show that flow field, erosion rate, and deformation of elbow are all sensitive to the structural changes and inlet condition changes. Higher inlet rate, smaller curvature diameter ratio, or smaller pipe diameter leads to greater deformation, while slower inlet rate, larger curvature diameter ratio, and larger pipe diameter can weaken flow erosion.
