“…Next, the inflation dynamics of a Disk-Gap-Band (DGB) parachute in the low-density, low-pressure supersonic Martian atmosphere is simulated [61,62,4]. The main purpose of this simulation is to understand the effects of the suspension line subsystem on the parachute performance during the deceleration process.…”

“…Cable subsystems appear in a wide range of engineering and scientific applications, such as the suspension lines in parachutes and other atmospheric decelerators [1,2,3,4,5,6,7], offshore drilling and production risers [8,9,10] and airborne refueling systems [11,12,13,14]. When immersed in a flow, cable structures can be responsible for strong fluid-structure interactions that may significantly affect the performance of the system to which they are attached.…”

Cable subsystems characterized by one or more extremely long, slender and flexible structural elements are featured in numerous engineering systems including parachutes, suspension bridges, marine drilling risers, and aerial refueling equipment. In each one of these systems, interaction between the cable and its surrounding fluid is inevitable. However, the nature and consequences of such Fluid-Structure Interactions (FSI) have received relatively little attention in the computational mechanics open literature possibly due to an inherent complexity associated with resolution of the multiple scales present in problems of this type. This work proposes an embedded boundary approach for simulating the FSI of cable subsystems, in which the dynamics of the solid cable is captured by a discretization of the cable centerline using conventional beam elements which are typically available in commercial and open source finite element structural codes, while the geometry of the cable is represented within the fluid domain using a discrete -for instance, triangulated -embedded surface. The proposed approach is built on: master/slave kinematics between beam elements (master) and the embedded surface (slave); a highly accurate algorithm for computing the embedded surface displacement based on the beam displacement; and an energy-conserving method for transferring distributed forces and moments acting on the nodes of the discrete surface to the beam elements. Hence, both the flow-induced forces on the cable and the effect of the structural dynamic response of the cable on the nearby flow are taken into account. Moreover, the proposed model can be readily incorporated into the Eulerian computational framework, which enables handling of the large deformations of the cable subsystem. The effectiveness of the proposed approach is demonstrated using a model aerial refueling system and a challenging supersonic parachute inflation problem.

“…Fluid-Structure Interaction (FSI) problems are a wide spread topic in the applied mathematics community, and despite their instrinsic complicated nature (see for example [23,33]), they are frequently used for simulation purposes, such as, for example, in naval engineering [43], as well as in biomedical applications (as an example of the implementation of FSI in the medical field see [19,29,48,6,49,51,58,44,13]) and in aeronautical engineering (see for example [52,21,24,41,1,15]). The complex nature of these coupled problems is reflected not only in their theoretical treatment, but also in the way they are solved numerically.…”

The goal of this manuscript is to present a partitioned Model Order Reduction method that is based on a semi-implicit projection scheme to solve multiphysics problems. We implement a Reduced Order Method based on a Proper Orthogonal Decomposition, with the aim of addressing both time-dependent and time-dependent, parametrized Fluid-Structure Interaction problems, where the fluid is incompressible and the structure is thick and two dimensional.

“…Indeed, despite their instrinsic complicated nature (see [18,19]), FSI problems are frequently used in everyday life: in naval engineering, they are used to study interactions between the water and the hull of a ship [20]; in biomedical applications, FSI problems are used to model the interaction between the blood flow and the deformable walls of a vessel [21][22][23][24][25][26][27]. Finally, in aeronautical engineering, FSI describes the way the air interacts with a plane or with (parts of) a shuttle; see [15,[28][29][30].…”

The aim of this work is to present an overview about the combination of the Reduced Basis Method (RBM) with two different approaches for Fluid–Structure Interaction (FSI) problems, namely a monolithic and a partitioned approach. We provide the details of implementation of two reduction procedures, and we then apply them to the same test case of interest. We first implement a reduction technique that is based on a monolithic procedure where we solve the fluid and the solid problems all at once. We then present another reduction technique that is based on a partitioned (or segregated) procedure: the fluid and the solid problems are solved separately and then coupled using a fixed point strategy. The toy problem that we consider is based on the Turek–Hron benchmark test case, with a fluid Reynolds number Re=100.
