Multi-Disciplinary Analysis of a Strip Stabilizer using Body-Fluid-Structure Interaction Simulation and Design of Experiments (DOE)

Abstract

The stability of aerospace vehicles is one of the concerning subjects for aerospace engineers and researchers and there are different solutions for the stabilization purpose including rigid and flexible stabilizers use. Design and analysis of such systems generally need multidisciplinary analysis tools and also efficient design strategies. The first goal of this paper is to develop a computational framework for the simulation of bodyfluid-structure interactions (BFSI) due to the oscillations of a flexible stabilizer connected to the end of body. For analyzing fluid-structure interactions, an iterative partitioned coupling algorithm is utilized. With combining a dynamic simulation tool for body motions, the ultimate multidisciplinary framework is arranged. As the second goal of the work, for the sensitivity analysis and also constructing a cost-efficient basis for parametric study, the design of experiments (DOE) methodology is implemented. The proficiency and efficiency of computations is evaluated with the results obtained in a variety stabilizing conditions and various strip characteristics such as length, width, and bending stiffness. The results of different simulations shows that the proposed framework is capable to capture the multi-physic nature of the problem with reasonable cost, especially useful for frequent analyses needed during product design and development loops.

FSI in Wind Turbines: A Review

“…Most of the turbine aeroelastic analyses have carried out the utilization of engineering techniques the place the blade forces are often computed via the BEM notion and additionally the dynamic stall was once modeled with empirical fashions like the ON-ERA or the Beddoes-Leishman models. The dynamic response of the turbine used to be as soon as thereafter determined the use of structural computational gear [5,7,9].…”

“…The 2D evaluation gave a stall attitude of about eight degrees, however, the 3D analysis, it being greater accurate, did now not supply us with a stall angle. The effects of the 3D full meeting evaluation of vertical axis wind turbines have been incomplete [8].…”

“…The theoretical fashions based totally on beam fashions mostly consist of the four-equation model, six-equation model, eight-equation model, twelve-equation model, and fourteen-equation model. These fashions are solely relevant for the lowfrequency acoustic conduct of linearly elastic, fluid-filled pipes of round cross-section [10]. An eight-equation mannequin approves for axial (longitudinal) and lateral (flexural) wave propagation alongside every pipe in the device [35,62].…”
