“…It has been checked that integral parameters obtained for the case of study are very similar to the numerical ones in [11] despite the minor differences in the value of the turbulence intensity and numerical settings. Furthermore, the results obtained herein are aligned with the experimental results reported in the same reference.…”

“…3 COMPUTATIONAL APPROACH The deterministic samples of the quantities of interest, that are latter used in the stochastic collocation, are identified by means of CFD simulations. To this end, 2D URANS simulations are conducted for the short-gap twin-box deck named as g22 case in [11], which has been adopted as case of study (see Section 4 for details). The turbulence model of choice has been k-ω SST.…”

“…Wang and Dragomirescu [17] tested a new type of multi-box bridge deck in the wind tunnel for static force coefficients, flutter derivatives and critical flutter wind speed. Nieto et al [18,19] performed a parametric investigation on the slotted cross sections to apply the analytical optimum design problem formulation to optimize the cross section. Multi-objective optimization algorithm have been presented in [20] to obtain Pareto optimal solutions for a bridge cross section by using CFD simulations to minimize the aerodynamic forces.…”

“…It is well known that a complete characterisation of the aeroelastic behaviour of the PV panel is not feasible using URANS simulations. Nevertheless, it is common practice [14] to employ engineering models that are computationally affordable, and it is therefore meaningful to inquire within what limits they are reliably applicable; a similar approach was adopted, for example, in [15]. The use of unsteady RANS simulations to analyse the wind structure interaction is growing in many engineering applications [16][17][18][19]; the majority of these are related to structural studies on fundamental components of rotating machines.…”
